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 says “a good oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Mix the batter
Beat the egg yolks and whites together for 2 minutes.
Add the sugar and beat for 5 minutes.
Mix in the flour and cream of tartar, then beat for 2 minutes.
Add the cold water and baking soda, then beat for 1 minute.
Stir in the grated lemon rind and juice, then add the flour and beat for 3 minutes.
Bake
Bake in deep cupcake pans in a 400°F (200°C) oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped to trap air, giving the cake its light, airy structure.
- Sugar
- Adds sweetness and helps stabilize the beaten egg foam.
- Flour
- Provides the starch and gluten that set the cake's structure as it bakes.
- Cream of tartar
- Its acidity stabilizes the egg whites so the foam holds up during beating.
- Baking soda
- Reacts with the acidic ingredients to release gas that helps the cake rise.
The step that matters
Adding the flour and beating for 3 minutes. Once flour is in, beating develops gluten in the batter. Overbeating at this stage can make the cake tough and dense, and it can also deflate the air trapped in the eggs.
