Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to stiff foam, they give the puff balls their light, airy structure.
- Baking powder
- Releases gas when heated, helping the batter balls swell and rise.
- Flour
- Gives the stiff batter body so each ball holds its shape while cooking.
- Butter
- Adds richness and fat, softening the crumb and carrying flavor.
- Milk
- Moistens the batter and helps bind it to a workable consistency.
The step that matters
Cover tightly and boil for 10 minutes. Keeping the lid on traps steam so the balls puff and cook through. Lifting the lid lets steam escape, which can stop them rising and leave them dense.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
