BRIOCHE PASTE
One cake of compressed yeast, a pinch of salt, one and one fourth cupfuls of butter, four cupfuls of flour, one tablespoonful of sugar, two tablespoonfuls of warm water, and seven eggs. Dissolve the yeast in the water, adding a little more water if necessary, and rubbing the yeast cake with a spoon until thoroughly dissolved. Stir in enough sifted flour to make a stiff dough, rolling and patting with the hands until thoroughly mixed. Drop this ball of paste into a kettle of warm water and let stand in a moderate temperature until it has a little more than doubled in bulk. (Some recipes for Brioche say that the ball of paste should be light enough to float.) Put the remainder of the four cupfuls of flour into a mixing bowl, add the sugar, salt, and butter, softened but not melted, and four of the eggs, unbeaten. With the hand mix carefully to a paste, beat smooth, and add the rest of the eggs, unbeaten, one at a time. Take the ball of paste, when light, out of the warm water with a skimmer, and, still using the hand, incorporate it carefully with the egg mixture, folding the two together as lightly as possible. Let rise, in a moderate temperature, until double in bulk. Then turn the paste on a floured board and pat and fold with the hands until smooth in texture and inclined to stay in shape. Let rise once more until very light, then put into the refrigerator and let stand over night.
