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 two or three waters and trim them.
Fill a saucepan with plenty of warm water and bring it to a boil.
Boil
Once boiling, add the salt and baking soda.
Add the sprouts and boil quickly for 10 to 20 minutes, depending on their age. Keep the lid off the saucepan while boiling.
Drain the sprouts in a colander.
Finish and serve
Once dry, place them in a sauté pan with the butter.
Sprinkle with pepper and salt, and toss over the heat for a few minutes without frying.
Serve arranged nicely on a hot vegetable dish.

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 their dense leaves until tender.
- Baking soda
- Raises the water's alkalinity, helping the sprouts keep a bright green color while boiling.
- Butter
- Adds fat and richness, coating the sprouts as they are tossed in the pan.
The step that matters
Boil quickly with the lid off. Sprouts need a fast, vigorous boil in plenty of water so they cook evenly and stay green. Leaving the lid off lets volatile sulfur compounds escape, reducing the strong cabbage-like smell and bitterness.
