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 ↓
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.
Prepare the cake
Preheat the oven to 350°F (175°C).
In a bowl, mix sugar, flour, eggs, cream of tartar, and baking soda until smooth.
Divide the batter into 8 layers.
Bake until golden.
Make the cream
Heat milk in a saucepan.
In a separate bowl, whisk together eggs, flour, cornstarch, and sugar.
Slowly add the egg mixture to the hot milk, stirring constantly until thickened.
Let the cream cool before spreading it between the cake layers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure to the sponge and thicken the cream as they set with heat.
- All-purpose flour
- Forms the structure of the sponge and thickens the cream.
- Sugar
- Sweetens the cake and helps keep it tender and moist.
- Cream of tartar
- Stabilizes the egg foam and helps the batter rise evenly.
- Baking soda
- Reacts to create gas that helps the cake rise and brown.
- Cornstarch
- Thickens the cream so it sets smoothly when cooled.
The step that matters
Adding the egg mixture to the hot milk. Pouring the eggs in too quickly or without constant stirring can scramble them. Stirring steadily while adding the mixture lets the starch and egg proteins thicken the cream evenly and smoothly.
