Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Baked Halibut
Ingredients
Directions
Prepare the fish
Soak the halibut in a strong saltwater solution for at least 1 hour.
Wipe the fish, then cut the skin on top in a criss-cross pattern, reaching the flesh.
Bake and baste
Place the fish in a dripping pan and pour boiling water over it.
Cook for 12 minutes per pound, basting often with a mixture of melted butter and lemon juice.
Check for doneness by inserting a fork into the thickest part; it should penetrate easily.
Remove the fish and keep it warm.
Make the gravy
For the gravy, add Worcestershire sauce and butter mixed with browned flour to the drippings.
If the gravy is too thick, add a little boiling water, boil, and strain into a sauceboat.

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 body of the dish, cooked gently in steam and drippings until flaky.
- Butter
- Adds richness and moisture, and carries flavour when basted over the fish and into the gravy.
- Lemon juice
- Adds acidity that brightens the basting mixture and balances the richness of the butter.
- Browned flour
- Thickens the gravy and adds a toasted, nutty flavour to the drippings.
The step that matters
Checking doneness with a fork. Halibut is lean and dries out quickly once it passes flaky. Testing the thickest part with a fork, rather than relying only on the timed estimate, helps keep it moist.
Swap the lemon
How well each one fits the dish's main ingredients (butter, sauce, flour):
- Raisinfits better
- Avocadofits better
- Coconutfits better
- Lemonthe original
Fit is the average pairing score against butter, sauce, flour. Candidates are from the same food group and used in at least 100 recipes.
