Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Halibut Steak Baked with Tomatoes
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.
Make the sauce
Make a rich sauce by cooking tomatoes with butter, flour, sugar, pepper, onion juice, salt, and minced green pepper for 15 minutes.
Strain the sauce through a colander.
Let the sauce cool.
Prepare the fish
Marinate the halibut in oil and lemon juice for 1 hour.
Place the halibut on a grating in a covered roaster.
Bake and serve
Pour the sauce over the halibut.
Cover the roaster.
Bake for 12 minutes per pound at 400°F (200°C).
Sprinkle Parmesan cheese over the fish.
Cook for an additional 5 minutes.
Serve hot.
Pour the sauce over the halibut.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Form the body of the sauce and provide moisture and acidity for the fish.
- Butter
- Adds richness and fat to the sauce.
- All-purpose flour
- Thickens the sauce as it cooks.
- Halibut steak
- The main protein, which cooks gently in the covered roaster with the sauce.
- Parmesan cheese
- Adds savory flavor and browning on top of the fish.
The step that matters
Cool the sauce before pouring it over the fish. Flour thickens the sauce as it cooks, and pouring it over fish while still very hot can cook the surface unevenly. Letting it cool first, as the record directs, keeps the sauce spoonable and the fish texture gentle.
Swap the onion
How well each one fits the dish's main ingredients (tomato, butter, flour, sugar, pepper, lemon, parmesan cheese):
- Capsicumfits better

- Onionthe original
Fit is the average pairing score against tomato, butter, flour, sugar, pepper, lemon, parmesan cheese. Candidates are from the same food group and used in at least 100 recipes.
