Why it works: Mustard and celery are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 4,169 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Dixie Relish
Ingredients
Directions
Prepare the vegetables
Soak the sweet red and green peppers in brine (1 cup salt to 1 gallon water) for 24 hours.
Freshen the peppers in clear cold water for 1 to 2 hours, then drain well.
Remove seeds and coarse white sections from the peppers, chop separately, and measure the chopped cabbage, peppers, and onions.
Combine and stand
In a large bowl, combine the chopped vegetables with mustard seed, celery seed, sugar, and vinegar.
Cover and let the mixture stand overnight in a crock or enameled vessel.
Pack and process
Pack the relish into small sterilized jars, pressing it carefully.
Drain the vinegar off the relish before packing to ensure the jars are well filled.
Pour the drained vinegar over the packed relish, ensuring all air bubbles are removed.
Garnish each jar with two quarter-inch strips of red pepper, placing them vertically on opposite sides of the jar seams.
Cap, clamp, and process the jars for 10 minutes at boiling temperature.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vinegar
- Provides the sharp acidity that gives the relish its tang and helps preserve it.
- Sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Mustard seed
- Contributes a pungent, slightly bitter bite to the relish.
- Celery seed
- Adds a savoury, aromatic celery flavour.
- Cabbage or chayote
- Adds bulk and a crisp, crunchy texture to the relish.
- White onion
- Adds sharp flavour and crunch that stands up to the vinegar.
The step that matters
Packing the jars full and free of air bubbles. Packing firmly and removing trapped air leaves less empty space in the jar, so the relish stays submerged in vinegar and the jar seals properly during processing.
Swap the onion
How well each one fits the dish's main ingredients (mustard, celery, sugar, vinegar, cabbage, pepper):
