GATEAU BRETON

Steps:

• Preheat the oven to 375 degrees F (190 degrees C). Grease a 9-inch springform pan.
• Mix 1 teaspoon egg yolk and water in a small bowl. Set aside for glazing the cake.
• Combine remaining egg yolks, flour, butter, sugar, and cornstarch in a large bowl. Mix with an electric mixer until dough is stiff and sticky, similar to cookie dough. Knead dough a little bit to bring it together.
• Press dough into the prepared pan with your hands. Brush glaze on top.
• Bake in the preheated oven for 15 minutes. Reduce temperature to 350 degrees F (175 degrees C). Continue baking until golden brown, about 25 minutes more. Cool for 10 minutes. Slice cake crosswise.

GATEAU BRETON

Steps:

• Place the flour on the counter and make a well. Cut up the butter and place the sifted sugars, butter, yolks, rum, and vanilla powder in the well. Work the well together.
• Work in the flour then "fraisage" the dough, pushing it away from you on the counter with the heel of your hand. This helps schmear the butter into thin layers to make the cake flakey in the end. Chill the dough 30 minutes.
• Preheat the oven to 360 degrees F.
• Butter an 8-inch cake pan and line the bottom with parchment and butter the paper. Roll the dough out on a lightly floured surface to an 8-inch disk about 1/2-inch thick. Flip it over onto your hand and brush off the excess flour then place it in the pan. Brush the top with egg wash; then egg wash it again to get a thicker coating. Using a knife, decorate it with the traditional cross-hatching, or for restaurant presentation you carve a map of Brittany on the surface and do some angled lines all around the edge. Bake until golden brown, about 30 to 40 minutes. Let cool in the pan and serve in wedges.
• I kept this recipe in the original metric measurements I was taught it in to show the relationship between the ingredients. Quatre-Quarts (meaning "four quarters") is a French cake shaped like a rectangle and all the ingredients (butter, sugar, flour, and eggs-oooo that would make a good book title, don't you think?) are of equal weights. My teacher, Chef Claude at La Varenne said you weigh the eggs and then match that measurement with the other ingredients.
• If you look this up in the dictionary, Quarte-quarts translates to pound cake, the American version of a pound of 4 equal ingredients, but with air whipped in for leavening. This cake is dense and buttery with a big crumb, more like a shortbread than a cake.
• You can do the mixing in a food processor but this recipe is the traditional way.

WALNUT GâTEAU BRETON

Steps:

• 1. Preheat the oven to 300°F/150°C/gas 3/4. Butter and lightly flour a 9-inch/23-cm cake pan.
• 2. Place the walnuts and 2 tablespoons of the sugar in the bowl of a food processor and grind so that most of the walnuts are finely ground but not anywhere near a paste.
• 3. In a large bowl, whisk together 6 of the egg yolks and the remaining 1 cup 2 tablespoons sugar until the mixture is blended, just a few minutes; there is no need to use an electric mixer here. It will be thick and yellow but shouldn't form a ribbon. Slowly whisk in the walnuts and sugar, then the butter. Sift the flour over the mixture and whisk it in just until the mixture is homogeneous. Don't overmix the batter or the cake will be tough.
• 4. Whisk together the remaining egg yolk and 2 teaspoons water, to make an egg glaze.
• 5. Turn the batter, which will be quite stiff, into the prepared pan and smooth it out. Lightly but thoroughly paint it with the egg glaze. Using the back of the tines of a fork, deeply mark a crisscross pattern in the top of the cake, going three times across it in one direction, then three in another. (The marks in the cake will fade, leaving just their trace on the top of the cake.)
• 6. Bake in the center of the oven until the cake is deep golden on the top and springs back slowly but surely when it is touched, about 1 hour and 15 minutes. Using a knife or cake tester isn't recommended as it always comes out looking slightly damp because of the amount of butter in the recipe.
• 7. Remove from the oven and transfer the cake to a wire rack, and let it cool for about 10 minutes before turning out of the cake pan. Let it cool thoroughly before serving.
