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 sugar and beat for 6 minutes.
Mix in 2 cups of flour and cream of tartar, and beat for 1 minute.
Combine the cold water and baking soda, then beat for 1 minute.
Add the lemon rind, lemon juice, and 2 more cups of flour, along with salt.
Bake
Bake in a preheated oven at 350°F (175°C) for 20 minutes.

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 cake its light, airy structure.
- All-purpose flour
- Provides the starch and gluten that set the cake's structure as it bakes.
- Sugar
- Adds sweetness and, beaten with the eggs, helps hold air in the batter.
- Cream of tartar
- Acidifies the batter, stabilising the beaten egg foam and keeping it airy.
- Baking soda
- Reacts with the acidic ingredients to release gas, helping the cake rise.
The step that matters
Beating the eggs and sugar. Sponge cakes depend on air whipped into the eggs and sugar for lift, since there is little other leavening. Under-beating leaves a dense cake, and over-deflating the batter when adding flour and liquids loses that lift.
