Tofu in warm broth ミニ湯豆腐

It is getting cold. We decided to have a hot tofu dish called “Yu-dofu” 湯豆腐.  “Yu” means “hot water” and “dofu” is “tofu*. I am surprised to find out I never posted “Yu-doufu”. I deviated from a traditional “yu-dofu” a bit by seasoning the broth lightly and adding fresh shiitake mushrooms and scallion to the broth. I also served it with “Ponzu” ポン酢 as a dipping sauce. I served individual portions in mini-donabe  ミニ土鍋 (picture #1). This is the perfect dish for a cold night. 

*This is another example of “rendaku” 連濁, “yu+tofu”  becomes “yu+dofu” when making a compound word.

Ingredients (for 2 small mini-donabe servings)
2/3 block of medium firm (you can use silken or firm as well), cut into one inch cubes
450ml Japanese broth (I used a dish pack which contains kelp and bonito and re-enforced the flavoring by using additional squares of kelp)
1-2 tbs x4 concentrated Japanese noodle sauce
2 scallions, white parts chopped finely and the green parts cut into 1.5 inch segments
2 caps of fresh shiitake mushroom, sliced thinly

Directions:
Add the seasoned broth to individual mini-donabe on low flame.
When the broth is warm, add the cubes of tofu, shiitake mushrooms and chopped scallions.
Simmer gently for 5-10 minutes until the tofu cubes are throughly warmed. Add the green parts of scallions and simmer for another 2-3 minutes or until the greens are wilted.
Serve with the ponzu if desired.

I think using lightly seasoned broth and ponzu as a dipping sauce made the tofu a bit more flavorful. You can add more vegetables but then it may not be rightfully called “yu-dofu”. 

I realized I have a special perforated spoon and fork for serving yu-doufi as well as the container for dipping sauce which is used  half submerged  in the cooking broth in the center of the pot. We used them long time ago but almost forgot about it. I managed to find them (picture #2). 

In the traditional/classic “Yu-dofu”, add the water and kelp in the donabe pot, fill the dipping sauce container and place it in the center of the pot. Add the cubes of tofu in the kelp broth and let it simmer so that the tofu and the dipping sauce are both warmed up. The tofu is scooped up using the perforated spoon and fork and placed in the dipping sauce in the center and then moved to the your small bowl. The condiment is  usually chopped scallion. But bonito flakes, grated daikon and Japanese red pepper powder can be added. If you omit bonito flakes (in the broth and dipping sauce), then the dish is vegan.

We like the modification I made to this dish. The broth the tofu is cooked in has a nice “dashi” favors of kelp and bonito and seasoning it with the Japanese noodle sauce makes it nice to drink. Dipping the tofu in ponzu adds an additional dimention.

New Induction Cooker Compatible Do-nabe IH 対応、銀宝花三島万古焼土鍋

Japanese “Nabe” 鍋 hot pot is a dish that is cooked at the table while you eat.  Classically, a portable butane-canister gas cooker is used with a “Do-nabe”  土鍋 earthen-ware pot. We used to have a butane table top cooker for nabe and sukiyaki すき焼き but because of safety concerns, which mainly stemmed from the age of our canisters and cooker, we looked for an alternative which turned out to be a table-top induction cooker (or the Japanese term is “IH”, short  for induction heater). For this to work, you have to use IH compatible pots and pans. Traditional Japanese nabe earthen-ware pots are certainly not IH compatible. We eventually found an IH compatible nabe from Kinto which worked great. Only complaint (which may not be important to many) is that while the pot worked well it is a very modern-appearing ceramic and does not have the traditional look of nabe. (I missed the homey nostalgic feel of a nabe which just the sight of the traditional design pot can evoke for me.)

Recently, I found an IH compatible nabe which is made of traditional “Banko-ware” 万古焼 pot called “Gipo Hanamishima Banko-yaki pot” 銀宝花三島万古焼土鍋 in an on-line store called “Japanese taste”. This is where we got dried persimmon or “hoshigaki” 干し柿. The “Japanese taste” ships items directly from Japan but it comes relatively quickly*. In any case, we got this “IH compatible do-nabe” pot last year but did not have a chance to use it until now. In the picture below, the left is “Kakomi” IH donabe from Kinto and the right is new Ginpo IH compatible donabe.

*We later learned that this pot is available at Amazon USA.

To make a donabe IH compatible, a magnetic metal disk needs to be present between the induction cooker surface and donabe.  Both these induction compatible donabes took a bit of a different approach.

Kinto donabe has a metal disk embedded into the bottom of pot as seen below. It can be used on gas, induction, and or halogen (electric heating element) cook tops. But not in a microwave oven.

Gipo comes with a stainless steel perforated disk which snaps into the inside bottom of the pot (apparently Ginpo has a patent). There are metal hooks and the inside bottom of the pot is formed to accept and secure this disk. It can be removed for cleaning and using the pot in a microwave. We initially tried it on our old induction cooktop (at least 18 years old which works with our cast iron sukiyaki pot and  Kinto donabe). The Gipo donabe, however, did not work with the old induction cooker. The cooker issued an error message which essentially read “NO-CAN-DO”. I read the instructions that came with the Gipo donabe and found out that it may not be compatible with older IH cookers. Great. Which meant we would be getting a new table top induction cooker to complete the set. It was not too expensive.

The new one is much better; the surface is completely covered with glass and easy to clean and the controls are more advanced. The new cooker worked with the Ginpo donabe. Actually, it boiled the liquid inside much quicker. I assume that because the metal disk is in contact with the liquid.

We enjoyed our nabe dish.  The main protein was cod and oyster. The cod was great. The oysters, however, were a different story. Digression alert: We are having a difficult time getting good oysters, especially Pacific oysters. For this dish we got small (eastern) frozen oyster but they tasted terrible. Luckily they did not ruin the flavor of the rest of the nabe. We ended up throwing out the remainder of the oysters in the package.

The other items in the nabe included nappa cabbage, tofu, diakon, mushrooms (enoki, oyster, shiitake and shimeji). I also added “fu” 麩 gluten cake. I made a broth with dried kelp and a dashi pack and, and for a change, seasoned the simmering liquid with miso (miso, mirin and sake).

Somehow, this new do-nabe is esthetically more pleasing (at least for me) and works great. Since this is a genuine earthen ware pot, you should not keep the contents in the pot over night.

Seafood nabe on a snowy day 雪降りの夕の海鮮鍋

As the weather got colder our thoughts turned to having Japanese hot pot or nabe 鍋 for dinner. This week we had some snow and our backyard was transformed to a winter wonderland; perfect time for nabe. So we decided to have one using whatever ingredients we had on hand.

We used to cook nabes on a portable gas cooker with a butene fuel canister but both the cooker and the canisters became so old we started worrying about how safe they were. Fortunately after we used up the canisters several years ago. We switched to a table top induction cooker (or Japanese will say IH or induction heater).  Making Sukiyaki すき焼き on this type of cooker works well because a sukiyaki nabe pot is usually made of cast iron but other earthenware or pottery pots or nabes won’t work. Then, we discovered an induction-cooker-compatible nabe pot. (It has a magnetic metal disk embedded in the bottom). With it,  we can do a nabe at the table without having to use a gas canister fuel source. 

I checked our freezer and refridgerator and decided we could do a sea food nabe or “kaisen-nabe” 海鮮鍋. We defrosted, scallops, cod, pacific oyster (this is the second time we used frozen Pacific oyster which worked well as a fry) and shrimp. We also had fresh shiitake and  nappa cabbage but not other green leafy vegetables. In any case, we set up our nabe feast.

I started the broth by soaking kelp in the nabe pot in cold water for several hours.  In the evening, I put the pot with the kelp in it on the induction cooker. Once the water came to a boil, I removed the kelp. I then added the shrimp shells and once the color of the shells changed I continued simmering for a few minutes, I the removed the shrimp shells.  I seasoned the broth with white dashi “Shiro-dashi” 白だしand light colored soy sauce making a very gentle broth. I started cooking the hard part of the nappa cabbage as well as the other vegetables. We also had some decent firm tofu from Whole Foods which I added. Next came daikon, carrot and potato, all precooked in the microwave oven.

Our seafood lineup is shown below (all frozen, and thawed in the refrigerator). It included shrimp, scallop (from Great Alaska Seafood), Pacific oysters (from Vital choice wild sea food and organics) and cod (from Whole foods). This was the second time we used frozen Pacific oysters. The first time I made fried oysters.  These were much better than the small fragmented fresh or pasteurized  oysters we sometimes get.

The picture below shows the vegetables which waiting to be put into the nabe; the leafy portion of nappa cabbage, tofu, shiitake mushroom, precooked daikon, potato, and carrot. 

We made sure the seafood was not overcooked. We also used  ponzu sauce as we were eating. This was a fun dinner perfect with the snowy winter outside and the steaming body warming nabe inside. We had warm sake (“Hakutsuru Ginjo 白鶴吟醸) to boot. Of course, there were leftovers. Classically, Japanese will end the nabe by adding rice or noodles into the remaining broth to make a “shime” 〆 final dish but we were too full and the next day, we made rice porridge with eggs for lunch.

Warm sake and oden on a cold winter's evening 厳寒の冬の夕燗酒とおでん

Since we had some very cold wintery days recently, we enjoyed warm sake several times. One such evening, we had the Japanese classic of hot sake with oden. After I found Hakushika junmai and junmai ginjo 白鹿純米、純米吟醸 (sake in a box) at our Japanese grocery store, these have become our favorite sake served warm or "kanzake" 燗酒. The sake sold this way is usually not the best sake but is still good quality as is the case with these two. Also sake sold in a box costs significantly less than the same sake sold in a bottle. For these reasons, we think these are a good buy. (Other packaging variations may include "cup-sake" or "sake-in-a-can". Cup-sake could be even daiginjo class).

Of course on a cold winter evenings, warm sake is best paired with either oden おでん or nabe 鍋dishes. This time, I made oden. Usually boiled eggs in oden end up hardboiled even if they are soft boiled when put in the broth. So this time I made soft boiled eggs with runny yolks which I kept separate from the rest of the oden, then just 5 minutes before serving I warmed them in the broth.  I put mochi in the deep fried tofu pouches or "abura-age" 油揚げ. Instead of regular potato I used "sato imo" 里芋 or taro.

Although the eggs did not absorb the broth's flavor, the runny yolks were nice for a change. The cylindrical item is fish cake stuffed with burdock root or "Kobo-ten" ごぼう天.  The rest of the items were tofu, shitake mushroom, blanched broccoli and carrot.

On a cold winter evening, this is very warming and comforting.

Nabe cooked on an induction cooker, IH 適応土鍋で鱈ちり

Some years ago, when we remodeled our kitchen, and were exiled to cook in the basement for the duration of the construction, we got a tabletop induction cooker.  We also had a butane canister gas table top cooker from our days in California. Although we used it for Nabe and Sukiyaki dishes, the gas cooker and the canisters were almost 30 years old and we were worried about their integrity.  Despite their age, they seemed to work fine but we did not buy extra gas canisters after we used them up.  Although our Sukiyaki pot was cast iron and compatible with induction cooking, we could not use our Japanese "Donabe 土鍋" earthen pots. So I just cooked our nabe dishes on the regular gas range and served them at the table which is not as much fun as tabletop cooking.

Induction cookers are much more popular in Japan than in the U.S. and are called "induction heaters" or "IH" for short.  As a result,  IH-compatible "donabes" have been available in Japan for some time.  Although I wanted to purchase one, as far as I know,  it is expensive to ship to the U.S. even if the Japanese companies would be willing to ship it.  Then, I came across Kinto store where they sell rather modern design Japanese table- and kitchenware. One of these items is an IH compatible Nabe (it came in two colors - black or white and two sizes - 40 and 82oz).

Instead of traditional earthenware, this is made of a much less porous heat-resistant porcelain with a special induction compatible plate embedded on the bottom. It comes with a steamer insert as well. It was reasonably priced and above a certain price break-point, shipping was free. I bought a small nabe (40oz) with some other items (so shipping was free). It is not a traditional design but we like the modern and clean line. This nabe can be used on gas, electric heating element, induction or in the oven. So, I took out our old induction cooker and decided to make "Cod and vegetable nabe" or "Tarachiri" 鱈ちり鍋 on the table. I would have used edible chrysanthemum or shun-giku 春菊  as a green if it had been available but I could not get it.  So, I used a small bunch of whole spinach. I also added scallion, fresh shiitake 椎茸 and hen-of-the-wood 舞茸 mushrooms, nappa cabbage 白菜 and tofu 豆腐.

 I got some black cod filets with the skin removed.  If the skin had not been removed (but hopefully cleaned and scaled, which is not always the case, here, when the skin is left on the fish) it would have helped hold the the fish meat together better and added a different texture and flavor. I salted the filets a few hours prior to cooking and kept them in the refrigerator uncovered before cutting them into chunks.

As condiments, I prepared thinly sliced scallions and grated daikon with Japanese red pepper (the daikon turned out to be too spicy for us).

For a change, we cooked and ate this in our sunroom. The pictures were not really good since it was getting dark and the lighting was quite dim by the time we had this.

Traditionally, the cooking liquid is just kelp broth without seasoning and the cooked food is served with "ponzu" dipping sauce and the garnish.  I made a minor deviation and made the broth with kelp and dried bonito flakes and added sake, mirin and a small amount of "usukuchi" light colored soy sauce. I first put in the vegetables and tofu and when they were almost done, I added the cod.

We used Ponzu sauce (from the bottle). As I mentioned the grated daikon was too spicy even without the red pepper flakes. We really enjoyed the tabletop cooking. There is something very comforting about the steam rising from the pot, the soft sound of the the liquid bubbling and lovely cooking smells. We ate much more than we thought we would. In Japan, the end of this nabe dish would include adding noodles or rice to the remaining broth, which, by the end of the dinner, would have built up some very nice flavors from the vegetables and fish or whatever ingredients were cooked in the pot. This broth was exquisite; very complex and slightly sweet from the veggies. Although it was really good we were too full for more than a few sips to taste let alone adding noodles or rice. Instead, the next day, we added rice to the leftover broth and whatever was left in the pot and made rice porridge with the addition of eggs as a lunch. With that we felt we had done justice to the nabe.
