Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Ribbon Cake
Ingredients
Directions
Sift the baking powder into the flour.
Cream the butter and sugar until light, then add the milk.
Gradually mix in the beaten egg whites and flour alternately.
Divide the batter into four equal parts.
Flavor one part with bitter almond for the white layer.
Color another part pink with cochineal and flavor with rose water.
Beat the yolks of two eggs and add to the third part, flavoring with lemon extract for the yellow layer.
Mix the Baker's chocolate with a little water and stir into the fourth part for the dark layer, flavoring with vanilla.
For the icing, dissolve 1 pound of sugar in 1½ cups of water and boil until it ropes.
Pour the syrup gradually into the beaten egg whites, beating until cool and flavoring with vanilla.
Stir in the grated coconuts.
Spread the icing between each layer and on the top and sides of the cake.
Layer the cake starting with the chocolate layer at the bottom, followed by the yellow, pink, and white layers.
