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
- Bass
- The main protein, cooked gently in the poaching liquid until it flakes.
- Drawn butter
- Adds richness and a smooth, fatty mouthfeel to the finished fish.
- Vinegar
- Adds acidity to the poaching liquid, flavouring the fish as it cooks.
- Lemon juice
- Brightens the butter sauce with acidity that cuts through its richness.
The step that matters
Heat the pot slowly for the first 30 minutes. Gentle, gradual heating keeps the fish from toughening and splitting as the proteins set. Starting the fish in a rapid boil can make the outside cook too fast while the centre stays underdone.
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.
