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 ↓

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 batter lift and a light, airy structure.
- Sugar
- Sweetens the batter and helps stabilise the beaten eggs.
- Flour
- Forms the structure that holds the batter's shape as it sets.
- Cream of tartar
- Acidifies the batter, stabilising the whipped eggs and aiding rise.
- Baking soda
- Reacts with the acid in the batter to produce gas, helping it rise.
- Lemon juice
- Adds acidity and bright flavour that balances the sweetness.
The step that matters
Dissolving the baking soda in the water before adding it. Baking soda must be fully dissolved and mixed in evenly so it reacts with the acid throughout the batter. Unevenly distributed soda leaves pockets that over-rise or taste bitter, and the rise depends on that reaction happening in the batter before baking.
