Why it works: Vanilla and sugar are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Boiled Sponge Cake
Ingredients
Directions
Prepare
Beat the whites and yolks separately and then beat them together.
Boil the sugar in a quarter of a cup of water until clear.
Make the batter
Slowly pour the boiled sugar into the beaten eggs, a little at a time, to avoid cooking the eggs, and beat until cool.
Stir in the flour. Do not beat after adding flour; just stir.
Bake
Bake for three-quarters of an hour in a slow oven.
Nutrition, whole recipe (rough)
Counts 6 of 7 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten eggs trap air, giving the cake its light, risen structure.
- Sugar
- Sweetens the cake and helps keep its crumb soft and tender.
- Flour
- Sets during baking to give the sponge its firm structure.
- Vanilla
- Adds a warm, aromatic flavor to the cake.
The step that matters
Pouring the boiled sugar into the eggs. Hot sugar syrup can cook egg proteins and turn them lumpy. Adding it slowly, a little at a time, while beating lets the eggs warm gradually and blend smoothly.
