Why it works: Cream and sugar 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 ↓
Cream Sponge Cake
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.
Mix the batter
Beat the eggs in a coffee cup.
Fill the cup with cream.
Add sugar, flour, cream of tartar, and baking soda.
Flavor with lemon.
Mix until well combined.
Bake
Pour into a prepared baking pan.
Bake at 350°F (175°C) until golden and a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and lift, trapping air and setting as the cake bakes.
- Flour
- Forms the structure that holds the cake's crumb once baked.
- Sugar
- Sweetens the cake and helps keep the crumb tender and golden.
- Cream
- Adds moisture and richness to the batter.
- Cream of tartar
- Acidifies the batter, stabilizing egg foam and helping leavening react.
- Baking soda
- Reacts with the acid in the batter to release gas that makes the cake rise.
The step that matters
Mix until well combined. Once flour meets liquid, gluten begins to form, so mixing too long can make the cake tough. Stir just until no dry flour remains, and combine the baking soda and cream of tartar evenly so the cake rises uniformly.
