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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat the oven to 400°F (200°C).
In a large bowl, beat together the sugar and eggs until well combined.
Dissolve the baking soda in the cold water and add it to the mixture.
Stir in the cream of tartar.
Gradually mix in the flour until just combined.
Pour the batter into a prepared cake pan.
Bake
Bake for 30 minutes, testing with a broom straw; it should come out clean.
Do not remove the cake from the oven until it is fully baked to ensure it remains light.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten with sugar, they trap air and give the sponge its light, airy structure.
- All-purpose flour
- Its proteins form gluten and set the crumb once the cake bakes.
- Fine white sugar
- Beaten with the eggs, it helps hold air and adds sweetness and tender texture.
- Baking soda
- Reacts with the acidic cream of tartar to release gas that helps the cake rise.
- Cream of tartar
- Acidifies the batter so it reacts with baking soda, producing lift and a finer crumb.
The step that matters
Leaving the cake in the oven until fully baked. Opening the oven or removing the cake before the centre sets can cause the rising structure to collapse. Testing with a broom straw confirms the crumb is set and the cake will stay light.
