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 ↓

What each ingredient does
- Fresh summer squashes
- Forms the bulk of the dish and, once cooked and mashed, gives it a soft, moist texture.
- Butter
- Adds fat and richness, giving the mashed squash a smoother mouthfeel and a rounder flavor.
The step that matters
Mashing in a colander to remove excess water. Squash holds a lot of water. Draining it well after cooking keeps the mash thick instead of loose and watery, and lets the butter and seasoning cling to it.
