Why it works: Walnut and lemon match in chemistry and in kitchens. They rank in the top 10% of all ingredient pairs, and cooks put them together in 2,149 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Baked Halibut
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Soak the halibut in salt water for 2 hours.
Wipe the fish dry and cut the skin.
Place the halibut in a baking dish.
Bake
Bake in a 400°F (200°C) oven, basting often with butter and water.
Bake for 1 hour or until a fork can easily penetrate the fish.
Make the gravy and serve
Collect the pan gravy.
Add water if needed.
Stir in walnut catsup, Worcestershire sauce, and lemon juice.
Thicken the gravy with brown flour mixed with cold water.
Boil the gravy once.
Serve the gravy in a sauce boat.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Halibut
- Forms the main protein, which firms and turns opaque as it cooks.
- Butter
- Adds richness and moisture to the fish and pan drippings while basting.
- Brown flour
- Thickens the pan gravy so it coats the fish and spoon well.
- Walnut catsup
- Adds savory, tangy depth to the gravy.
- Lemon juice
- Adds acidity that brightens the flavor of the gravy.
The step that matters
Bake until the fish is just done. Halibut is lean and dries out quickly once it passes doneness. Checking for a fork to pass easily through the thickest part helps keep it moist and flaky.
Swap the lemon

Fit is the average pairing score against butter, walnut, sauce, flour. Candidates are from the same food group and used in at least 100 recipes.
