Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Bind the batter and help the puffs hold their shape as they cook.
- Butter
- Adds richness and flavor to the batter and to the finished puffs.
- Sour cream
- Adds moisture and tang, keeping the batter tender.
- Flour
- Provides the structure that holds the thick batter together while it cooks.
The step that matters
Keeping the batter very thick. A batter that is too thin will spread and fall apart in the boiling water instead of forming rounded puffs. Adding flour gradually lets you stop once the batter holds its shape when dropped from a spoon.
