Pain aux raisins is a French pastry that is made with standard bread dough that has been sweetened or brioche dough. A brioche has very high egg and butter content which makes it very rich and crumby.
The word soufflé came from the French word souffler, which means to puff up. A very apt description to this fluffy dessert, made primarily with beaten egg white, but more importantly - love and tenderly care.
