Why it works: Sugar and vanilla 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 ↓
Angel Cake
Ingredients
Directions
Prepare
Sift the fruit sugar 5 times.
Sift the flour, cream of tartar, cornstarch, and salt 5 times.
Make the batter
Beat the egg whites until foamy, then slowly add the sugar while continuing to beat.
Add the vanilla and lemon juice, then gently fold in the flour mixture, sifting it gradually over the egg mixture.
Pour the batter into an unbuttered tube pan.
Bake and cool
Bake in a slow oven at 275°F to 300°F (135°C to 150°C) for 1 hour.
Do not open the oven door during the first 20 minutes.
When done, invert the pan on a cake cooler and let the cake hang in the pan until cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into foam that traps air, giving the cake its light, airy structure.
- Flour
- Forms the cake's set structure once heated, holding the airy foam in place.
- Fruit sugar
- Sweetens the cake and stabilises the whipped egg white foam as it is added.
- Cornstarch
- Softens the crumb by diluting the flour's gluten, producing a tender texture.
- Cream of tartar
- Acidifies the egg whites, helping them whip to a stable, voluminous foam.
The step that matters
Folding in the flour mixture. Folding gently and sifting the flour in gradually keeps the whipped egg white foam from deflating. Overmixing knocks out the trapped air, which leaves the cake dense rather than light.
