Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red sweet peppers
- Provide the main body and sweet, fresh pepper flavor of the relish.
- Mustard
- Adds sharp, pungent flavor that balances the sweetness of the relish.
- Vinegar
- Provides acidity that gives the relish its tang and helps preserve it.
- Light brown sugar
- Adds sweetness and depth, balancing the acidity of the vinegar.
The step that matters
Cook until tender. Cooking over medium heat softens the peppers and lets the vinegar and sugar meld into a cohesive relish. Undercooked peppers stay firm and taste raw, while overcooking can scorch the sugar and make the mixture too thick.
Swap the mustard
How well each one fits the dish's main ingredients (pepper, vinegar, sugar):
- Capsicumfits better
- Mustardthe original
- Cabbagefits less well
- Cucumberfits less well
Fit is the average pairing score against pepper, vinegar, sugar. Candidates are from the same food group and used in at least 100 recipes.
