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 ↓

Fry and serve
Drop teaspoonfuls of the mixture into hot oil and fry until light brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the starch structure of the dough that holds the puffs together.
- Large egg yolks
- Add richness and fat, and help the dough bind and set into a tender interior.
- Butter
- Adds fat and flavor and keeps the dough tender when fried.
The step that matters
Adding the egg yolks one at a time. Each yolk must be fully blended before the next is added. Adding them too fast can split the dough, leaving it greasy and unable to hold its shape in the hot oil.
“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.
