Why it works: Butter and parsley are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 28,563 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Brussels Sprouts
Ingredients
Directions
Prepare
Wash and trim the Brussels sprouts, then soak in cold water with salt for a few minutes.
Drain the sprouts well and place them in a large saucepan of boiling water with baking soda and a little salt.
Cook and serve
Boil quickly until tender, about 20 minutes, then drain thoroughly.
Place the boiled sprouts in a hot dish and serve hot.
If desired, return the drained sprouts to the saucepan with butter and parsley, tossing over gentle heat for a few minutes before serving.

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 body of the dish; they soften into tender, mild-tasting vegetable during boiling.
- Butter
- Adds richness and a silky coating that carries flavor across the sprouts.
- Baking soda
- Raises the water's alkalinity, which helps the sprouts keep a bright green color while cooking.
The step that matters
Boil quickly until tender. Overcooking breaks down the sprouts' cell walls and releases sulfur compounds, causing a grey color and strong smell. A rapid boil and prompt draining keep them green and fresh-tasting.
