Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 29,058 recipes. Both carry furaneol, which smells caramel, strawberry. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red fish or red snapper
- Forms the main body of the dish, cooking gently in the wine sauce until flaky.
- Claret wine
- Provides liquid and acidity that build the sauce and flavor the fish.
- Butter
- Adds richness and fat, helping onion and flour brown and carry flavor.
- Flour
- Thickens the sauce so it clings to the fish rather than running thin.
- Red onion
- Adds aromatic sweetness and depth when cooked until light brown.
- Mushrooms
- Contribute moisture and savory, earthy flavor to the sauce.
The step that matters
Cooking the sauce well before adding the fish. Cooking the wine and flour mixture long enough cooks off raw flour taste and thickens the sauce, so the fish is added to a stable, flavorful base rather than a thin, floury liquid.
Swap the tomato
How well each one fits the dish's main ingredients (fish, butter, onion, garlic, flour, parsley, celery):
- Chivefits better
- Leekfits better
- Shallotfits better
- Tomatothe original
Fit is the average pairing score against fish, butter, onion, garlic, flour, parsley, celery. Candidates are from the same food group and used in at least 100 recipes.
