Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Form the bulk of the pickle and, once salted and drained, give it a firm texture.
- Coarse sea salt
- Draws moisture out of the tomatoes and onions, firming them before pickling.
- Vinegar
- Provides the acidity that preserves and sharpens the pickle.
- Coffee sugar
- Adds sweetness that balances the sharp vinegar and spices.
- White mustard seed
- Adds pungent flavour and a slight bite to the pickling liquid.
The step that matters
Drain after salting and before pickling. Salt draws water out of the tomatoes and onions; if they are not drained well, excess liquid dilutes the vinegar syrup and softens the pickle.
Swap the onion
How well each one fits the dish's main ingredients (tomato, vinegar, mustard, coffee, sugar, allspice, cinnamon):
- Capsicumfits better
- Horseradishfits better
- Cucumberfits better
- Onionthe original
Fit is the average pairing score against tomato, vinegar, mustard, coffee, sugar, allspice, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
