Hazelnut Olive Oil Cake ヘーゼルナッツ、オリーブオイルケーキ

The other day, while we were grocery shopping at Whole Foods, my wife came back with “Hazelnut meal” and “Coconut flour”. She was obviously very curious about these fancy flours; specifically, what were they used for and what did they taste like? It appears that these nuts meal/flours are mostly used for gluten free (GF) cakes and cookies. In any case, she looked for recipes using that used hazelnut meal and found  this hazelnut olive oil cake recipe. This is a very moist cake with a distinctive hazelnut flavor and also slight olive oil flavor. We really like it and the flavors got better with time.

The cross section shows very moist and succulent interior.

This gluten-free and daily-free (GF, DF) recipe came from an on-line site called the recipetineats. I will ask my wife to take over.

Ingredients
150g / 5oz hazelnut meal (1 3/4 cups firmly packed) (almond meal can be substituted)
1/2 tsp baking soda sifted
Zest of 1 lemon, finely grated (about 2 teaspoons or so)
Pinch of salt
1/2 cup + 1 1/2 tbsp extra-virgin olive oil (medium quality is OK)
1 cup sugar
3 large eggs , at room temperature
2 tsp vanilla extract

Directions
Preheat oven to 340°F. Grease a 20 cm/8" springform pan with olive oil then line with baking paper (parchment paper), then grease the paper. In a medium bowl, mix the hazelnut meal, baking soda, lemon and salt. In a large bowl, beat the olive oil, eggs and sugar for 2 to 3 minutes on speed 7 or 8 until it becomes pale and thick (like pouring cream or runny mayonnaise). Add vanilla and beat on speed one for 10 seconds. Add the Dry ingredients and mix in gently using a rubber spatula. Pour the batter into the prepared pan and bake for 45 minutes. It will puff up dramatically in the oven but it collapses as it cools. Remove from the oven and allow the cake to fully cool in the pan before releasing from the springform pan. This is a rustic cake that has higher edges and a flatter centre.

This cake is very moist and has a lovely slightly sweet nutty hazelnut flavor with a background flavor of olive oil. The olive oil adds to rather than overwhelms the overall experience. Interestingly, although this cake was very good right out of the pan it got better and better with time. The flavors melded together and got richer. This went very well with a morning cappuccino.

Chestnut Flour Cake with Persimmons and Buttermilk チェストナッツフラワーと柿のケーキ

This is an another cake my wife made from the new chestnut flour.   She came across the recipe using chestnut flour, persimmons, and buttermilk. Since we happened to have all these ingredients, she went for it. The cake was very moist and had nice chestnut flavor but the persimmon flavor is very subtle (i.e. not discernible at all). It was not too sweet and perfect for breakfast.

Ingredients:
172 grams chestnut flour
148 grams or 5.2 ounces of persimmon puree. *
1/2 cup buttermilk (we used my wife favorite buttermilk from Harrisburg dairies.)
3 eggs, at room temperature
1/4 cup melted unsalted  butter
1 tsp vanilla extract
generous pinch of salt
1 tsp baking powder

* The persimmon came from Weee (#1 below). They are “Fuyu” 富有柿 (which is pronounced “fuyuu” meaning “wealthy”) variety and are called chocolate fuyuu because of the dark brown color of the fruit. They were not expensive but they were small with seeds. (Most commercially grown Fuyu persimmons are seed-less). They were irregular in shape with dark blemishes which made them look like they came from somebody’s backyard tree. But when ripened they are very good with pudding-like consistency and sweet. Only problem was that it was very difficult to remove all the seeds/stones.

Directions:
Preheat oven to 350°F (177°C). Butter 9" cake pan. (Having learned from our previous experience with the chestnut flour cake we added a buttered piece of parchment paper to the bottom of the pan and the cake came out of the pan with no problem) 
Puree the persimmon and set aside (#2). Sift chestnut flour to remove any larger bits/chunks.
Mix dry ingredients in bowl and set aside. Using either an electric mixer or a bowl whisk and beat the eggs. Add other wet ingredients. Fold dry ingredients into wet ingredients until fully incorporated (#3).
Pour batter into buttered pan and put into pre-heated oven for about 30 minutes, until the cake is firm in the middle and a toothpick pulls out clean. Remove from oven and cool on baking rack for at least 30 minutes before serving (#4). We reheated in the microwave for 15 seconds (First picture).



This cake was very moist, slightly sweet with a dense texture. The nutty chestnut flavor came through but we couldn’t identify any persimmon taste. This was a very good addition to breakfast.

Castanaccio Pugliese (Chestnut Flour Cake) カスタナチオ

We like pancakes for breakfast sometimes. One of the unusual ones we like to make is chestnut flour pancake”. Since we are now in the chestnut season, we decided to have the chestnut flour pancake for breakfast one weekend. We keep all exotic and whole grain flours including the chestnut flour in a small freezer in the basement. When my wife got it out, she realized its BUB (best used by) was in 2015. It smelled ok. We went ahead and made the pancakes which were very good but even by our standards this flour was a bit too far past its BUB. We decided it is the time to buy a new batch. We got a couple of bags of chestnut flour and my wife looked for some new recipes to use it. She came across this recipe for chestnut flour cake on-line. Actually, she made a chestnut flour cake with the same Italian name “Castagnaccio” previously. But that cake was quite different from this one. It was very savory and did not use any leavening agent, or sugar but did use fresh rosemary which provided good flavor. Overall, however, we were not crazy about it because it was rather dry and crumbly. The new recipe she found must be a variation of an Italian generic cake called castagnaccio. In any case, the major differences are this cake uses a leavening agent, sugar and coco powder. Instead of herbs such as rosemary this used a combination of nuts and candied fruit. It is much thicker as well. This version is more suitable for breakfast or dessert than the previous version which was more savory and as the original recipe suggested “should be washed down with red wine”. The common thing is that both cakes are quite crumbly. (We ended up eating both of them as crumbs with a spoon.)

Ingredients
1 1/2 cups chestnut flour
1/3 cups sugar
1 tablespoon baking powder
2 tablespoons cocoa powder, plus more for dusting
Pinch of salt
1/2 cup extra virgin olive oil, plus more for brushing
2 tablespoons honey, plus more for serving
2 large eggs
1 cup milk
1 cup of Harry and David’s medley of candied fruit. (The original recipe calls for 1/2 cup raisins and 1/2 cup dried cranberries, plumped in 1/4 cup warm water or wine - preferably Vin Santo).
1/3 cup toasted pine nuts
1/3 cup roughly chopped toasted walnuts (As added measure we added chopped chestnuts)
Confectioner's sugar for dusting

Directions:
Preheat oven to 350F degrees. Prepare a 9-inch cake pan (The original recipe suggested lightly greasing it with olive oil but we had trouble getting the cooked cake out of the pan. We suggest next time greasing the bottom of the pan and adding a layer of greased parchment paper.)
Toast the pine nuts and walnuts. In a large bowl, swift together the flour, sugar, baking powder, cocoa powder and salt. In a separate bowl, whisk together the olive oil, honey, eggs and milk. Slowly pour the liquids into the dry ingredients, whisking very well to avoid lumps. The batter should be smooth and a bit liquid. Add the nuts and dried fruit. Pour the batter into the prepared pan, and bake for 35 minutes, or until the cake begins to puff slightly and the middle is set. Remove from the oven and cool completely before removing from pan.
Dust lightly with confectioner's sugar and cocoa powder and serve with some warm honey.

We found it was difficult to remove the cake from the pan. A portion of it stuck to the pan and crumbled. (See the picture below). (Next time, we will use buttered parchment paper on the bottom of the pan). Even the portion that came out in one piece was difficult to cut into wedges since it kept crumbling. The only good thing was that even the crumbs tasted good.

Although eaten in crumbs this cake was very good. The chestnut flour added a nuttiness to the overall chocolate flavor. The pine nuts, walnuts and dried fruit added little bursts of flavor and texture. The dried fruit was particularly nice because it added a burst of sweetness. Interestingly, over time the chestnuts we added became rock hard and we had to be careful to remove them from every mouthful. We liked this cake better than the previous version my wife made. It would just be nice if it did not disintegrate into crumbs.
