Why it works: Tarragon and mustard match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 901 recipes. Both carry methyleugenol, which smells clove, spice. The science ↓
Zouave Sauce
Ingredients
Directions
Prepare
Mince the onions and fry them lightly in hot fat, then drain them and place them in a clean stew-pan.
Make the sauce
Add the tomato purée, brown sauce, and vinegars; bring to a boil and skim off any fat.
Season with salt, French mustard, and Tabasco pepper sauce to taste.
Stir in the chutney and quartered raisins, then simmer until the onions and raisins are tender.
Add a little brown stock as needed.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Soften and add savoury body and a little sweetness as they cook down into the sauce.
- Tomato purée
- Adds concentrated tomato flavour, colour and body to the sauce.
- Brown sauce
- Provides the rich, savoury base and body that the sauce is built on.
- Tarragon vinegar
- Adds acidity that brightens the sauce and balances its richness.
- Sultana raisins
- Add mild sweetness and soft, plump texture as they simmer.
The step that matters
Simmer until the onions and raisins are tender. Onions and raisins need enough time in the simmering liquid to soften fully. Stopping early leaves a coarse texture and a sharper, less rounded flavour in the finished sauce.
Swap the raisin
How well each one fits the dish's main ingredients (onion, tomato, sauce, tarragon, vinegar, mustard, pepper):
- Avocadofits better
- Limefits better
- Cherryfits better
- Raisinthe original
Fit is the average pairing score against onion, tomato, sauce, tarragon, vinegar, mustard, pepper. Candidates are from the same food group and used in at least 100 recipes.
