Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Trap air and provide structure, so the batter rises and holds its shape.
- Sugar
- Sweetens the batter and helps trap air when beaten with the eggs.
- Flour
- Forms the gluten network that gives the cake its set crumb.
- Baking powder
- Releases gas in the batter, lifting the cake as it bakes.
- Cold water
- Adds moisture to loosen the batter.
The step that matters
Beating the eggs and sugar. Beating the eggs and sugar for the full time traps air in the batter. That trapped air expands in the oven and gives the sponge its lift, so under-beating leaves a dense cake.
