Why it works: Cream and sugar 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 ↓
Original Berwick Sponge Cake
Ingredients
Directions
The book says “a good oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the yolks of the eggs until thick and lemon colored.
Add sugar and beat well, then mix in the cold water and lemon extract.
Sift the cream of tartar and baking soda with the flour three times, then stir it in lightly.
Beat the egg whites until stiff and gently fold them into the mixture.
Bake
Bake in a 350°F (175°C) oven for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks add richness and color, while whipped whites give the cake its light, airy structure.
- Flour
- Provides the starch and gluten that form the cake's main structure as it bakes.
- Sugar
- Sweetens the cake and helps keep it tender and moist.
- Cream of tartar
- Stabilizes the beaten egg whites so they hold their volume.
- Baking soda
- Reacts with acidic ingredients to produce gas that helps the cake rise.
The step that matters
Folding in the egg whites. Whites must be beaten until stiff, then folded gently. Overmixing knocks out the air that gives sponge cake its lift, leaving a dense crumb.
