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 ↓
Brussels Sprouts
Ingredients
Directions
Prepare
Wash the Brussels sprouts well in salt water and trim them.
Boil
Place the sprouts in a saucepan of boiling water with salt and carbonate of soda.
Boil uncovered until tender, about 10 to 20 minutes depending on age.

Finish and serve
In a stewpan, combine the sprouts with butter, salt, and pepper.
Toss until heated through, ensuring they do not fry.
Serve immediately.

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's main body; they soften during boiling and take on flavour from the butter.
- Butter
- Adds richness and a silky coating to the cooked sprouts.
- Carbonate of soda
- Raises the water's alkalinity, which helps the sprouts turn tender and keep a bright green colour.
The step that matters
Boil uncovered until tender. Sprouts vary in age and size, so cooking time changes. Overcooking makes them soft and sulphurous, while undercooking leaves them firm in the centre.
