Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Brussels Sprouts
Ingredients
Directions
Prepare
Remove the outer leaves from the Brussels sprouts.
Bring 3 quarts of salted water to a boil, adding the carbonate of soda.
Add the sprouts and boil again, then drain them on a sieve and a dry cloth.
Make the sauce
In a pan, brown 1 ounce of butter with the flour and sugar.
Add the stock, chopped onion, parsley, pepper, nutmeg, and the remaining butter.
Cook
Bring to a boil, then add the sprouts and simmer gently for 30 minutes.

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; simmering softens them and lets them absorb the sauce.
- Butter
- Adds richness and a rounded, savoury flavour when browned with the flour.
- Flour
- Thickens the stock into a smooth sauce once cooked briefly in the browned butter.
- Stock
- Provides the liquid for the sauce and carries savoury flavour into the sprouts.
- Carbonate of soda
- Raises the water's alkalinity, which helps the sprouts keep a bright green colour.
The step that matters
Browning the butter with the flour. Flour must cook in the hot butter while stirred, so it toasts evenly without burning or forming lumps. Undercooked flour tastes raw, and scorched butter turns the sauce bitter.
