Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Angel Cakes
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Mix and sift together the sugar, flour, and cream of tartar.
Do not grease the angel cake pans; instead, dip them in water and fill while damp.
Make and bake
Add the sifted mixture to the stiffly beaten egg whites and fold gently.
Bake in the preheated oven until done.
Immediately turn the pans upside down after removing from the oven; place a match under one side to let steam escape.
Finish
Once cool, remove the cakes from the pans and ice with water icing, fondant, or egg white icing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into a foam that gives the cake its light, airy structure.
- Sugar
- Sweetens the cake and helps stabilize the batter's structure.
- Flour
- Provides the structure that holds the cake's airy crumb once baked.
- Cream of tartar
- Acidifies the egg whites, helping the foam stay stable and hold its volume.
- Corn starch
- Softens the flour's gluten, giving the cake a tender, delicate crumb.
The step that matters
Inverting the pans immediately after baking. The hot, delicate egg-white structure is still setting and can collapse as it cools. Turning the pans upside down while the cake is hot lets it cool stretched, keeping its height and light texture.
