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 them in cold water with salt for a few minutes.
Drain the sprouts and place them in a large saucepan of boiling water with a tiny piece of baking soda and a little salt.
Cook
Boil quickly until tender, about 20 minutes, then drain thoroughly.
Serve
Place the 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
- The main vegetable; its dense leaves become tender and sweet when boiled.
- Baking soda
- Raises the water's alkalinity, helping the sprouts keep a bright green colour while boiling.
- Butter
- Adds richness, a glossy coating and savoury flavour to the drained sprouts.
The step that matters
Boil quickly until tender, then drain thoroughly. Overcooking breaks down the sprouts' cell walls, making them soft and grey and releasing strong sulfur compounds. Draining well prevents excess water from diluting the butter and parsley.
