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, Boiled
Ingredients
Directions
Prepare
Clean the Brussels sprouts, removing any insects and discolored leaves.
Boil
In a large saucepan, bring 4 gallons of water to a boil and add the salt and baking soda.
Add the sprouts to the boiling water and keep the pan uncovered.
Boil the sprouts quickly until tender, about 10 to 15 minutes.
Drain and serve
Drain the sprouts and serve immediately with melted butter or toss them in butter with a seasoning of pepper and salt.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brussels sprouts
- Form the main vegetable; cooking softens their dense structure until tender.
- Butter
- Adds richness and a smooth fat coating that carries flavor.
- Baking soda
- Raises the water's alkalinity, helping the sprouts stay bright green while cooking.
The step that matters
Boil the sprouts quickly until tender. Overcooking breaks down the cell walls and releases sulfur compounds, giving a mushy texture and strong smell. A fast, vigorous boil in uncovered water cooks them evenly while keeping flavor and color.
