Why it works: Butter and onion are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 42,912 recipes. Both carry decanal, which smells soap, orange peel. The science ↓

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 baking in boiling water.
- Melted butter
- Adds richness and moisture while basting the fish's surface.
- Brown roux
- Thickens the pan liquid into a smooth, body-rich sauce.
- Claret
- Adds acidity and wine flavor to the finished sauce.
- Lemon juice
- Adds acidity that brightens the buttery basting mixture.
The step that matters
Bake for 12 minutes per pound. Fish is done when it turns opaque and flakes easily; overbaking dries the flesh because proteins tighten and release moisture. Check early, since thickness varies.
Swap the lemon
How well each one fits the dish's main ingredients (butter, onion):
- Avocadofits better
- Coconutfits better
- Mangofits better
- Lemonthe original
Fit is the average pairing score against butter, onion. Candidates are from the same food group and used in at least 100 recipes.
