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 cheese cloth dampened with cold water.
Place the halibut in a strainer over a kettle of boiling water, cover closely, and keep the water boiling until the fish is done.
The fish is cooked when the flesh separates from the bone.
Make the sauce
To make the sauce, melt ¾ tablespoon of butter, add ¾ tablespoon of flour, and mix well.
Gradually pour in ½ cup of boiling water while stirring constantly.
Season with salt, then add ¾ tablespoon of butter in small pieces and the sliced hard boiled egg.
Serve
Transfer the fish to a hot serving dish, remove the skin, and pour around Drawn Butter Sauce.

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 by steam until the flesh separates from the bone.
- Butter
- Melted with flour to form a roux and later added in pieces to enrich the sauce with fat and flavour.
- Flour
- Mixed with melted butter to form a roux that thickens the boiling water into a smooth sauce.
- Hard boiled egg
- Sliced into the finished sauce, adding soft texture and mild richness.
The step that matters
Keep the water boiling under the strainer. Steam from a steady boil cooks the fish evenly and gently. If the water drops, the fish cooks slowly and unevenly, and the flesh may not separate cleanly from the bone.
