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 ↓
Berwick 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 2 minutes.
Add the powdered sugar and beat for 5 minutes.
Stir the cream of tartar into 2 cups of flour, then add it to the egg and sugar mixture and beat for 1 minute.
Dissolve the baking soda in the cold water and add it to the mixture.
Wash and dry the lemon, then add both the juice and grated rind.
Finally, add the remaining 2 cups of flour and beat all ingredients together for 1 minute.
Bake
Pour the batter into two deep cake tins and bake in a moderate oven at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped with sugar to trap air, giving the cake its light structure.
- Flour
- Provides the gluten and starch network that sets the cake's structure as it bakes.
- Powdered sugar
- Sweetens the cake and helps stabilise the whipped egg foam.
- Cream of tartar
- Stabilises the egg foam and adds a slight acidity to help the cake rise evenly.
- Baking soda
- Reacts with the acid in the batter to produce gas, helping the cake rise.
The step that matters
Beating the eggs and sugar. Whipping eggs and sugar thoroughly traps air bubbles that expand in the oven. Under-beating leaves a dense cake, while the later flour must be folded or beaten gently so the air is not knocked out.
