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 with Tomato Sauce
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the fish
Wipe the halibut and sprinkle with coarse sea salt and black pepper.
Place in a buttered pan and cover with the fat salt pork, gashed several times.
Bake and serve
Bake at 400°F (200°C) for 12 to 15 minutes.
Remove the fish to a serving dish, discarding the pork.
Make the tomato sauce
In a saucepan, cook the tomatoes, onion, clove, and a few grains of salt and pepper for 8 minutes.
Remove the onion and clove, then run the mixture through a sieve.
Add a few grains of baking soda and cook until the tomato is reduced to 2 teaspoons.
Pour the sauce around the fish and garnish with parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Halibut
- Is the main protein, cooked gently in the oven until flaky.
- Tomatoes
- Provide the base of the sauce, adding acidity and body as they reduce.
- Butter
- Greases the pan so the fish does not stick and adds richness.
- Fat salt pork
- Covers the fish during baking, adding fat and savory flavor that bastes the fish.
- Baking soda
- Neutralizes some tomato acidity, softening the sauce and changing its color.
The step that matters
Reducing the tomato sauce to 2 teaspoons. Cooking the sauce down concentrates its flavor and thickens it. Baking soda reacts with the tomato's acid and foams, so add only a few grains and watch closely, since too much will make the sauce taste soapy.
Swap the clove
How well each one fits the dish's main ingredients (pepper, butter, pork, tomato, onion, parsley):
- Thymefits better
- Garlicfits better
- Celeryfits better
- Clovethe original
Fit is the average pairing score against pepper, butter, pork, tomato, onion, parsley. Candidates are from the same food group and used in at least 100 recipes.
