Why it works: Butter and pepper are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 85,593 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brussels sprouts
- Form the dish; boiling softens their dense cabbage-like texture until tender.
- Butter
- Adds richness and a silky coating that carries flavor across the sprouts.
The step that matters
Drain and press gently to remove excess water. Water left on the sprouts dilutes the melted butter and seasoning, so they taste watery instead of coated and savory.
