Onsen egg with “Mozuku” in sweet vinegar 温泉卵とモズクの甘酢

This is a variation on the theme of “Onsen” egg 温泉卵. I put this dish together in a hurry on a weekday evening after work. I thawed a package of frozen “mozuku” もずく in sweet vinegar on the previous weekend but we did not eat it (we had other items and could not get to it). Since I also had a pair of "Onsen" eggs that  I had made using my Sous Vide machine, I decided to combine them into a starter dish.



I divided the mozuku into two bowls, cracked open and dropped an onsen egg into each bowl, garnished it with thinly sliced scallion, "real" wasabi and a drizzle of  "noodle" sauce or mentsuyu 麺つゆ from the bottle. That's it.



The egg yolk was nicely creamy and this combination worked very well. For this dish, we had to have cold sake.

Sous vide pork loin 豚ヒレ肉のスービィ

We like pork tenderloin and cook it regularly. Our most common way of cooking is to bake it slowly in a 350F oven (often the toaster oven in convection mode) for about 30 minutes or longer to an internal temperature of 140F. (The recommended USDA temperature has been modified and is now 140F). I often use a dry rub of cumin, smoked paprika, cinnamon, nutmeg, black pepper and salt with minor variations. This low temperature baking appears to make it moist and tender. Since we got a sous vide machine, I wanted to cook pork tenderloin in sous vide.

After  sous vide cooking at 140F (60F) for 3 hours (135 to140F for 2-3 hours according to the recipe I read). We need to consider food safety but at 135F-140F (maintained for some time) pathogenic bacteria such as salmonella should not be a problem. Cysticercus* also should not be a problem. After taking it out of the vacuum pouch, I grilled it briefly on a hot charcoal fire. I did this just because it was such a nice day, the mosquitoes are not out yet and we decided to grill using the Yakitori grill. Otherwise, I could have just briefly seared the surface using a frying pan.

* Cysticercus can be effectively eliminated by freezing. At -20C (-4F), the usual temperature of a household freezer, pork will be safe from cysticercus after one week, reportedly. (Madeleine Kamman used to say "not 20 days but after 21 days").  For heating, at 135F-140F (57-60C) maintained for 30 minutes or more, cysticercus should be also all deactivated (Reportedly 45-50C for 15-20 minutes is sufficient)



Since we had other food, we just tasted two slices each. It was quite moist and tender but the big question was "Is it better than our usual slow-baking method?" I am not sure. I may have to try it at 135F to see if that makes a significant difference.

After I generously rubbed the tenderloin with my dry rub ( cumin, smoked paprika, cinnamon, nutmeg, black pepper and salt), I vacuum packed with thin pats of unsalted butter as you can see below.



I placed this in my sous vide machine at 140F and cooked it for 3 hours. After I removed it from the pouch, I seared/grilled it over hot charcoal fire. I poured au jus (with melted butter) over the slices.

This is certainly not bad but the time and effort it takes, we are not sure if this is worth it. We may stick to our low temperature oven method.
P.S We used this pork for sandwiches several days after we cooked it. My wife commented that she detected a slightly “off” flavor to the meat and didn’t want to finish the sandwich. I got out the plastic bag in which I stored the meat and asked her to give it a “sniff test”…my wife has an extremely keen sense of smell. She recoiled from the package and said the smell was terrible; almost like ammonia. I have to say it didn’t necessarily smell bad to me, but I have learned that she can detect smells long before I can. In general it was not a good endorsement. That was the end of that tenderloin. While the tenderloin was quite all right immediately after coming out of the sous vide, it appears that it may not last as long as when we use our usual slow cook method. With that method the meat is good for up to a week. I guess the vote is in; we won’t be using sous vide for pork tenderloin again. 

Sous vide chicken breast 鶏胸肉のスービィ

Chicken breast is popular especially since it is reported to be healthier for you than red meat. One problem with chicken breast meat is that it is very easy to over cook and become dried out. In addition it is not easy to cook chicken breast evenly without under or overcooking. We particularly like the ones from barbecued whole chicken in Weber grill and chicken paillard, since the breast meat is mostly moist and succulent.  But after reading about how sous vide chicken breast is moist with juices running down etc,  I wanted to try sous vide chicken breast. The below is chicken breast cooked in sous vide at 140F for 3 hours and then skin seared/browned. It is indeed moist and nice. I served it with white and green asparagus with kimisu sauce left over from our sake tasting. I also made a quick pan sauce.


The current USDA guide line for cooking chicken is 165F but if you maintain the temperature for a specified longer duration, you can safely cook chicken at much lower temperatures. The amount of fat in the meat is also another factor (meat with more fat requires more time or a higher temperature). This chart indicates that for chicken breast, at 165F-160F, salmonella is killed almost instantly (i.e. as soon as the meat reaches this temperature, it is safe to eat) and at 140F you have to maintain the temperature for more than 30 minutes but less than 40 minutes. So if you use sous vide and maintain the given temperature for the specified duration, you should be able to cook chicken (or other meats) safely at lower temperatures than indicated by the USDA guide line. (Again try at your own risk).

I prepared bone-in skin-on split chicken breasts by removing the bone and tenderloins (for other use), trimmed the excess skin and fat but left most of the skin covering the breast meat intact. After I blotted away any excess moisture using a paper towel, I generously seasoned with salt (I used Hawaiian red salt since I had it) and freshly cracked black pepper. I then vacuum sealed it (left) using my edge-type "Food Saver" vacuum sealer.

It sealed with a good vacuum. I preheated my Anova sous vide machine  at 140F which took only few minutes since I started with the hottest water out of our tap. I placed two vacuum sealed chicken breasts into the heated water and let it cook for 3 hours (as per the recipe, at least for 2 hours). I am estimating that the internal temperature of the center of the thickest part of the chicken would be at 140F after 30 minutes (or at the most, 1 hour. Actual "cooking" or coagulation/denaturing of proteins must take more time to occur at this temperature).

When the chicken breast came out, the meat was opaque and only a small amount of juice was seen in the pouch (left upper in the picture below).



I removed the chicken from the pouch. After blotting any moisture from the surface (upper right), I seared the skin side on high heat with a small amount of vegetable oil (lower left). After 1 minute, I flipped the pieces showing nice brown color (lower right) and set it aside on a plate. I then poured the juice accumulated in the pouches in the same frying pan and briefly reduced (since the pan was hot this took only 20-30 seconds). I finished the sauce with a few thin pats of cold non-salted butter. Since some salt and pepper came off the chicken into the sauce and the chicken was well seasoned, I did not add any more seasoning.


The cut surface was just very slightly pink and very moist (actually not as pink as shown in the picture). Again, we had other dishes and we just tasted a few slices with the pan juice I made. The result was better than my sakamushi 酒蒸し or sake-steamed chicken breast (especially when I use the  microwave to make it, In the microwave the chicken breast sometimes comes out stringy with over cooked areas). I was impressed by how quickly the skin browned. It must be because it had already cooked and was warm and I blotted any moisture before searing (evaporation of liquid cools the surface and make searing/browning slower). Although, this time, this was a test run of sous vide chicken breast, with this success, I will try this as a more complete chicken dish.

Grilled sweet pepper stuffed with pork ペッパーのにら豚肉詰め

This is a variation of something I posted before, pork stuffed sweet pepper. Last time, my wife did not like the skin of the pepper—she thought it was too tough. Since I had access to the charcoal fire in our Yakitori grill one weekend, I decided grill the pepper and remove the skin for this dish. I also modified the stuffing especially because spring has arrived and garlic chives are growing in our herb garden.



We added a combination of smoked cheddar and gruyere cheese on the top.



This time, without skin on the pepper and nice flavor of garlic chives, this dish was better received.



Sweet pepper: I used an entire package of small sweet peppers (9 or 10). I grilled them on a hot charcoal fire until the surface blackened. Then I placed them in a Ziplock bag. I let them steam and cool. After the peppers were cooled, I removed the skin (which was relatively easy). I made a single slit along the length and removed the seeds (like two in the front, picture above).

Stuffing: The ground pork was from the trimmings of a pork tenderloin which I hand-chopped. The amount is all arbitrary since I did not measure any of the ingredients. I sautéed finely chopped onion, shiitale mushrooms, ginger, garlic and garlic chives in vegetable oil for a few minutes seasoned with salt and pepper. After the cooked ingredients cooled to room temperature, I mixed them into the ground pork. I added a small amount of sesame oil, soy sauce and hand mixed it. I stuffed each pepper with the meat filling.

Baking: I first baked it without cheese at 350F for 20 minutes. I then added cheese slices on top (smoked cheddar and gruyere) and baked 2-3 minutes or until the cheese melted (the first picture).

This time, my wife liked it  better since there was no tough skin on the pepper. The addition of  fresh garlic chives added a lot to the flavor. We will be eating the left over as a snack a for few more days. Perfect starter.

Shouchikubai Daiginjou Sake from California grown Yamdanishi 松竹梅大吟醸，米国産山田錦

Last time I posted G-sake and G-sake Fifty from SakeOne, Gordon kindly let me know that Takara Sake Co. 宝酒造 in Berkley were finally growing Yamada-nishiki 山田錦  in the Sacramento valley and were producing Junmai Daiginjo 純米大吟醸 . After some effort we finally got a few bottles directly from Takara. After I received my shipment, they restricted purchases to one bottle per order and then finally indicated they were out of stock. So, I guess, I was lucky.



The label reads, "Sho Chiku Bai*" Junmai Daiginjo 松竹梅純米大吟醸 brewed exclusively from California-grown Yamada-nishi 米国産山田錦全量 (polished to 45%). It is "unfiltered" Genshu 無濾過原酒 (i.e., undiluted with alcohol content of 16%) and is limited release 限定品. It had handwritten numbers and batch code(?) on the label.

*"Sho Chiku Bai" means Pine-Bamboo-Plum．This combination is considered a very auspicious in Japanese culture.



It happened that I received the sake just before a long holiday weekend and marked by some exquisitely pleasant sunny days. Consequently we had this tasting outside. As usual, we needed "otoshi" drinking snacks to enjoy this sake. I prepared a trio. From left to right; green asparagus (blanched) and chicken breast (barbecued in Weber, hand shredded) with "kimisu" 黄身酢 (egg yolk vinegar dressing), sashimi squid (frozen package) dressed with soy sauce, real wasabi and tobiko roe, and finally white asparagus with cream sauce (cream and reduced asparagus cooking liquid and butter).



This time, the  "kimisu" I made is a bit thicker and richer than before.



For frozen, the squid was not too bad and tobiko roe added an interesting texture.



The white asparagus requires a bit more preparation and cooking but the end result is sublime. The sauce really makes it…we didn’t leave any behind.


Now we were ready for sake tasting. We served this sake chilled. The color was clear. The sake had some floral aroma (Daiginjo smell), was nice and subtle with no distracting yeastiness. The palate was very clean with some subtle melon/apple and a hint of "umami" savory taste finishing with a slight sweet note.  It had a classic Yamada-nishiki daiginjo taste; clear and elegant. This one, I sensed, had a slightly bit more savory component than other daiginjo brewed from Yamada-nishiki such as our house sake "Mu" 無from Yaegaki 八重垣.

Albeit that this sake represented a very different price point, compared to recent batches of G-sake and G-sake fifty, this Sho Chiku Bai has a definitely more authentic daiginjo flavor profile and we like it much better. It is so smooth and easy to drink. Although we do not know what kind of California rice G-Sake is brewed from, I surmise that the sake rice they may be using must have more protein content since it has a strong savory taste. Yamada-nishiki, on the other hand, is known for its low protein content, thus, producing a cleaner and crisper taste in the resulting sake especially in the Daiginjo class. We also remembered that we tasted another daiginjo "Sho chiku bai" imported from Japan sometime ago and we were not as impressed with that as we are with the current sake. Compared to that daiginjo from Japan (which was more expensive), the all-American-daiginjo "Sho Chiku Bai" (may be except for the sake yeast) is indeed superior (and cheaper by $20).

All three otoshi appetizers went extremely well with this genuine American Daiginjo sake.  Hope we can “snag” several more bottles from next year's batch when they are released…BTW the line forms to the rear.

Indian-style Chicken curry with cream

This is another one of my wife's Indian-style curry. This is chicken curry with tomato and cream. I really like this one. We like to make this on the weekend and then quickly heat it up after coming home from a hectic day at work. Its nice to have such a hearty and flavorful dish waiting for us.


We needed something green for the photo.



Ingredients:
1/2 tsp cinnamon
1/2 tsp cardamom
1/4 tsp cloves
1/4 Tsp cumin seeds
3 bay leaves
3 Tbs fresh ginger diced
3 garlic cloves diced
2 onions diced
1 tbs ground coriander
1 tbs ground cumin
1 large can  plum tomatoes (reserve the juice)
4 chicken thighs deboned, skinned and cut into large cubes
1/2 tsp cayenne pepper
3/4 tsp salt
light cream (to taste). 

Several red potatoes (optional)

Take the first 5 ingredients and let them “bloom” in several tbs of hot oil (I use peanut oil). When they become fragrant add the chopped onions and sauté until they become translucent. Add the garlic and ginger continue sautéing careful not to burn the garlic. Once they have “bloomed” add the coriander, cumin, pepper and salt and allow them to “bloom”. Add the tomatoes and cook for a few moments. Then add the reserved tomato juice from the can. (If using the potatoes add them to the sauce and cook until they become a bit tender. Finally add the chicken. Make sure all the pieces are submerged in the sauce. Simmer gently until the chicken is tender (about 30 to 45 minutes). Just before serving add light cream to taste stirring it into the sauce.

This is one of our favorite curries. It uses almost all the spices on the shelf but the resulting layers of flavor make it worth while. The cream really evens everything out adding a mellowness. The chicken meat picks up all the flavors and is very tender—one of the best ways to cook chicken thighs which can be pretty chewy. We eat this with white rice.

Sous vide filet mignon

We heard that sous vide is the best way to cook a perfect steak. I have also heard "you can hold the steak at the desired doneness for a long time in sous vide without worrying about over cooking”. So, with high expectations, we tried sous vide filet mignon.

It appears that there are two methods of doing this. One is to cook the steaks in the sous vide first and them sear them. Another is to sear the steaks first and then sous vide them. With this method, the steaks are briefly seared again after coming out of the sous vide in order to “refresh” the crust. The advantage of the second method is that the first searing occurs when the meat is cold and uncooked which helps the searing process and cooks only the surface. In the first method, after the meat is sous vide cooked, the meat is warm and to developed enough crust, wider layers of over cooked meat will develop under the curst. I am not sure if this two methods make a big difference. But I decided to try the second method. I got two USDA prime filet mignons.

We served the steak with my wife’s oven fried potato, haricot verts (first blanched and then sautéed in garlic and butter). We could have done a better presentation (particularly with that blob of catsup) but it is too late.

I did the first searing using a small amount of vegetable oil on high heat for 30 seconds each sides. The filets came out directly from the refrigerator. After blotting off any juice/moisture, I vacuum sealed it (#1) using the edge type vacuum sealer. Towards the end of the vacuum sealing, some moisture got sucked out and the vacuum was not as tight as when I vacuum sealed dry items. Nonetheless it made a reasonable vacuum seal. Apparently if you use a “chamber” vacuum sealer, you can vacuum seal wet items better but that type of equipment is beyond my reach. For medium-rare, I set my ANOVA sous vide machine to 56C (133F) based on this recipe (#2). The thickest filet mignon was about 1.5 inches, so it should take about 90 minutes to cook. I set it to 3 hours instead, since that would put us at the right time for dinner. Also I trusted what I read that the steaks could be held for up to 6-8 hours without over cooking or deterioration of flavor.


After the steaks were cooked in the sous vide, I finished them by searing a second time. This time I used butter and sprigs of fresh thyme on high heat for 10-15 seconds each side basting with melted butter (#3). I then seasoned them with Kosher salt and freshly cracked black pepper. As you can see the nearly entire cut surface is nicely rosy pink with a very thin crust (#4). No over cooked surface areas or undercook center.

We think sous vide steak is much better than any we have tried. I usually cook steak by keeping the steak out at room temperature for 15-20 minutes and then searing it in a hot frying pan and finishing in the oven. This method is not bad but, definitely, produces an overcooked surface area and undercooked center even after resting the steak for 10 minutes.

This filet mignon was very tender with a nice crust but no bloody juice came out. The thyme was from our herb garden but we did not taste much of thyme flavor in the steak. Besides being a perfect steak, I think, the sous vide method is perfect for cooking steaks for a company dinner. You just hold the steaks in the sous vide until serving and quickly refresh the crust and serve. It is much easier than a frying-pan-to-oven method.  The only shortcoming may be that it is not possible to accommodate different doneness unless you have more than one sous vide machine.
