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
The book says “a steady oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Soak the halibut in salt water for 1 hour before cooking.
Wipe the fish dry and score it across the top with a sharp knife.
Bake
Place the halibut in a dripping pan and bake at 350°F (175°C) for about 1 hour.
Baste several times with hot water and melted butter.
Once done, transfer the fish to a hot dish.
Make the gravy and serve
Strain the gravy left in the pan and bring it to a boil.
Add 2 teaspoons of butter rubbed smooth with 2 tablespoons of browned flour to the gravy.
Just before removing from heat, stir in 1 tablespoon of Worcestershire sauce and the juice of 1 lemon.
Pour some gravy over the fish and serve the rest in a gravy boat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Halibut
- Forms the main flesh of the dish, cooking to flaky, moist fish when baked.
- Browned flour
- Thickens the strained pan juices into a smooth gravy with a nutty flavour.
- Butter
- Adds richness and moisture while basting and enriches the gravy.
- Lemon juice
- Adds acidity that brightens the rich gravy.
The step that matters
Adding the flour and butter paste to the gravy. Flour added directly to hot liquid clumps, so it must be rubbed smooth with butter first and whisked in while the gravy is boiling to thicken evenly.
Swap the lemon
How well each one fits the dish's main ingredients (butter, flour, sauce):
- Raisinfits better
- Avocadofits better
- Coconutfits better
- Lemonthe original
Fit is the average pairing score against butter, flour, sauce. Candidates are from the same food group and used in at least 100 recipes.
