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 ↓
Baked Halibut
Ingredients
Directions
Prepare the fish
Wash and dry the halibut steak, then season with coarse sea salt.
Bake the fish

Cook the sauce until thickened, then pour it around the baked fish.
Garnish and serve

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Halibut
- Firm, flaky protein that sets and turns opaque as it cooks, giving the dish its body.
- Butter
- Adds fat and richness, and carries the flour to form the sauce base.
- Flour
- Starch that swells with heat and thickens the butter and liquid into a sauce.
- Tomatoes
- Provide liquid, acidity and savory flavor to the sauce.
- Onion
- Adds aromatic, savory depth as it softens into the sauce.
- Almonds
- Add a nutty flavor and a slight texture to the sauce.
The step that matters
Cook the sauce until thickened. Flour thickens only when heated enough for its starch to swell. If the sauce is stopped early, it stays thin and can taste of raw flour. Cooking it fully gives a smooth, cohesive sauce.

Fit is the average pairing score against butter, flour, onion, pepper, almond, sugar, parsley. Candidates are from the same food group and used in at least 100 recipes.
