JULIA CHILD'S GENOISE CAKE

Steps:

• Brown butter in a saucepan, remove from heat to cool. Preheat oven to 325. Prepare 8x 2 pan--square or round. Butter, place parchment in bottom, butter the parchment. Whisk four eggs with sugar and vanilla over hot water until the mixture is warm to your finger. (The water in the bottom of the double boiler should not be boiling.) The mixture should be warm and foamy, not thick. Then place bowl beneath a stand mixer; mix 5-6 minutes until the mixture makes the ribbon. Next, alternately add the sifted flour and tepid butter to the batter, constantly and gently folding, taking care not to deflate the batter. Do not add the residual leavings of butter. Pour batter into the prepared pan, smooth with a spatula, and bake at 325 for 35-45 minutes. Cake is done when it rises and doubles, and springs back when you touch it. Cool 10 minutes, remove pan. When completely cool, cover. Can be frozen.
