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 ↓
Steamed Halibut
Ingredients
Directions
Prepare the fish
Clean the halibut by wiping it with a cheesecloth wrung out of cold water.
Place the fish in a strainer over a kettle of boiling water.
Cover the strainer closely.
Keep the water boiling until the fish is done.
Check that the fish is cooked when the flesh leaves the bone.
Take off the outside skin of the fish.
Remove the fish to a hot serving dish.
Make the sauce
Melt ¾ tablespoon butter.
Add ¾ tablespoon flour to the melted butter and mix the butter and flour together.
Gradually pour in ½ cup boiling water, stirring the sauce constantly.
Season the sauce with salt.
Add ¾ tablespoon butter in small pieces to the sauce.
Add the sliced hard-boiled egg to the sauce.
Serve
Pour the drawn butter sauce around the fish.

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
- Its flesh cooks gently by steam, staying moist and tender rather than drying out.
- Butter
- Melted into the sauce, it adds richness and a silky mouthfeel to the drawn butter.
- Flour
- Cooked with melted butter, it thickens the water into a smooth, pourable sauce.
- Hard-boiled egg
- Its sliced white and yolk add body and a mild, rich flavour to the sauce.
The step that matters
Keep the water boiling until the fish is done. Steam only cooks the fish while the water keeps boiling. If the kettle drops to a simmer or runs dry, the fish cooks unevenly or stalls, so keep the heat steady and check the flesh near the bone.
