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 ↓
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.
Make the batter
Beat the eggs for 5 minutes until fluffy.
Add sugar and beat for an additional 2 minutes.
Mix in the cold water, baking soda, cream of tartar, and flour until smooth.
Flavor with lemon extract to taste.
Bake
Pour the batter into a greased cake pan and bake at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten to trap air, giving the sponge its light, fluffy structure.
- Sugar
- Adds sweetness and helps the beaten eggs hold their foam while baking.
- Flour
- Provides structure as the batter sets in the oven.
- Baking soda
- Reacts with the acid in the batter to release gas, helping the cake rise.
- Cream of tartar
- Acidic ingredient that reacts with baking soda to produce lift and stabilizes the foam.
- Cold water
- Adds moisture to the batter, loosening it for an even texture.
The step that matters
Pour the batter and bake until golden. Once the baking soda and cream of tartar have been mixed in, the gas they release starts forming bubbles right away. Getting the batter into the pan and into the oven promptly helps keep those bubbles in the batter so the cake rises well.
