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
- The main vegetable; boiling softens its dense leaves until tender.
- Butter
- Adds fat, richness and flavour when the cooked sprouts are reheated.
- Baking soda
- Raises the water's alkalinity, which helps the sprouts soften and keep a bright green colour.
The step that matters
Boil until tender, then stop. Overcooking breaks down the sprouts' cell walls and releases sulfur compounds, leaving them mushy and smelling strongly. Checking for tenderness early and draining promptly keeps their texture and flavour better.
