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 ↓
Boiled Bass

Add vinegar, salt, onion, black peppercorns, and mace to the water.
Sew the fish in a piece of clean net that fits its shape.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bass
- Is the main protein that is cooked gently in the seasoned liquid until flaky.
- Drawn butter
- Adds richness and a smooth, moist mouthfeel to the finished fish.
- Vinegar
- Adds acidity that brightens the flavour of the poaching liquid.
- Lemon juice
- Adds acidity that brightens the butter sauce and balances its richness.
The step that matters
Heating the pot slowly. Bringing the water up gradually over the first 30 minutes helps the fish cook evenly and stay moist. Rushing to a hard boil can toughen the outside before the centre is done.
Swap the mace
How well each one fits the dish's main ingredients (vinegar, onion, butter, lemon):
- Tarragonfits better
- Parsleyfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against vinegar, onion, butter, lemon. Candidates are from the same food group and used in at least 100 recipes.
