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, softened by boiling until tender while keeping their shape.
- Baking soda
- Raises the water's alkalinity, helping the sprouts keep a bright green colour and soften faster.
- Butter
- Adds fat and richness, carrying flavour and giving the reheated sprouts a glossy coating.
The step that matters
Boil until just tender, then stop. Overcooking breaks down the sprouts' cell walls and turns them mushy and dull. Baking soda speeds this softening, so checking for tenderness early matters.
