Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

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).
Make the batter
Cream the butter and powdered sugar together until light and fluffy.
Beat the egg whites until stiff peaks form.
Gradually add the egg whites to the creamed mixture.
Sift the flour with baking soda and cream of tartar, then fold it into the batter.
Bake
Pour the batter into jelly cake pans.
Bake until a toothpick inserted in the center comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Powdered sugar
- Sweetens the cake and helps give it a fine, tender crumb.
- All-purpose flour
- Provides the structure that holds the cake's light crumb together.
- Butter
- Adds fat for richness and a tender texture.
- Egg whites
- Whipped to stiff peaks, they trap air that lifts and structures the cake.
- Baking soda
- Reacts with the acid in cream of tartar to release gas that helps the cake rise.
- Cream of tartar
- An acid that stabilizes the whipped whites and reacts with baking soda to aid rising.
The step that matters
Fold the flour into the batter gently. Fold only until no dry streaks remain. Overmixing develops gluten and knocks out the air in the whipped whites, which leaves the cake tough and dense.
