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 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
In a bowl, combine flour, cream of tartar, powdered sugar, and salt.
Make the batter
In the measuring cup used for flour and sugar, break in the eggs and beat for 2 minutes.
Fill the cup with sweet cream and add it to the flour mixture.
Dissolve baking soda in hot water and add to the mixture.
Beat well and pour into a prepared baking pan.
Bake
Bake until golden and slice the top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the structure that holds the sponge together as it sets.
- Eggs
- Trap air when beaten and set the crumb, giving the cake its lift and body.
- Cream of tartar
- Stabilizes the beaten eggs and works with baking soda to help the cake rise.
- Baking soda
- Reacts with the acidic ingredients to release gas, helping the cake rise.
- Sweet cream
- Adds moisture and fat, giving a tender crumb and richer flavor.
- Powdered sugar
- Sweetens the batter and contributes to a fine, tender crumb and browning.
The step that matters
Beating the eggs. Beating the eggs for the full two minutes traps air that gives the sponge its lift. Under-beaten eggs leave a dense cake, since the air bubbles are what expand in the oven.
