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.

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.

Steps:

• In a small pot over medium-high heat, combine prunes, rum and 2 tablespoons water. (Use 1 cup/240 milliliters water if using dried apricots.) Cook until most of the liquid has been absorbed (about 5 minutes for prunes, 10 to 15 for apricots). Use a fork to mash into a thick purée. Cover and chill.
• In a food processor, pulse to combine flour, sugar and salt. Add butter and pulse until mixture resembles bread crumbs. Add 5 egg yolks and pulse until mixture comes together as a dough. Divide in half, form into disks, and wrap in plastic wrap. Chill at least 2 hours or until firm.
• Heat oven to 350 degrees. Grease and line an 8-inch round cake pan with parchment paper. Between two sheets of parchment paper or plastic wrap, roll one of the dough halves into an 8-inch circle. Transfer dough to prepared cake pan, pressing into edges. Spread prune or apricot purée across dough, leaving 3/4 inch border around outside edge. Roll second piece of dough into an 8-inch circle, transfer to cake pan, press around outside edge to stick the pieces together and seal in fruit purée.
• In a small bowl, combine remaining egg yolk with 1 teaspoon water and beat lightly. Brush over top of cake, then use a fork to score a crisscross pattern into the dough. Bake until golden brown, about 50 minutes (cover with foil if cake is browning too quickly). Cool in pan 15 minutes. Flip onto a plate, then invert onto a wire rack and let cool completely.
