Why it works: Vinegar and onion are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 18,226 recipes. Both carry acetic acid, which smells sour, vinegar. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red snapper
- Is the main protein, cooked gently by poaching and steaming in the liquid.
- Vinegar
- Adds a light acidity that brightens the flavor of the cooking liquid.
- Small onion
- Adds aromatic flavor to the cooking water.
The step that matters
Covering the pan to steam the fish. If the fish is not fully submerged, the exposed part can dry out or cook unevenly. Covering the pan with another pan traps hot steam around it, so the portion above the water cooks gently and evenly.
Swap the onion
How well each one fits the dish's main ingredients (snapper, vinegar):
- Capsicumfits better
- Tomatofits about as well
- Onionthe original
- Mustardfits about as well
Fit is the average pairing score against snapper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
