Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms a starch paste that gives the batter enough body to hold its shape.
- Egg yolks
- Add richness and emulsify the dough, helping it stay smooth and tender.
- Egg whites
- Trap steam as the puffs fry, lifting them to a light, hollow interior.
- Butter
- Adds fat for flavour and a tender, short texture.
The step that matters
Drop the mixture into boiling fat. The fat must be very hot so the outside sets quickly and steam inflates the puff. In cooler fat the batter soaks up oil, turns greasy, and stays dense.
