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 ↓

Ingredients
Directions
Make the batter
Break the eggs into a dish.
Add sugar, flour, baking powder, and cold water.
Beat the mixture until it is thin and bubbling, then add flavoring.
Bake and roll
Divide the batter between two pans and bake.
Once baked, spread with jelly and roll up.

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
- Whipped into the batter, they trap air and give the sponge its structure.
- Sugar
- Adds sweetness and helps keep the sponge tender and moist.
- Flour
- Forms the gluten network that gives the sponge its set structure.
- Baking powder
- Releases gas during baking, helping the sponge rise and stay light.
- Cold water
- Adds moisture and loosens the batter so it spreads thinly in the pans.
The step that matters
Beating the batter until thin and bubbling. The air whipped into the eggs is what makes the sponge rise and stay light. Under-beaten batter bakes dense, and an over-baked sponge cracks when rolled.
