Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓
Sponge-cake
Ingredients
Directions
Weigh 8 eggs and use the same weight in pounded loaf sugar and ⅔ cup of flour.
Separate the yolks from the whites of the eggs.
Beat the yolks and place them in a saucepan with the sugar, stirring over low heat until dissolved.
Remove from heat and add the lemon zest and brandy, mixing well.
Gradually fold in the flour until fully combined.
