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 ↓
Sweet Relish
Ingredients
Directions
Prepare the vegetables
Grind all the vegetables separately using a food chopper.
Press out all surplus juice and sprinkle salt on each vegetable; let them stand.
Make the relish
Boil the vinegar with grated nutmeg, cinnamon sticks, brown sugar, whole spices, and black pepper. Strain the spices from the vinegar and combine the vegetables in an aluminum or granite kettle.
Cover and cook for 10 minutes.
Add a little green fruit coloring to improve the color.
Seal the jars
Pour hot paraffin wax over the top and seal in pint self-sealing jars.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Provide the bulk of the relish and its fresh, tart body once cooked.
- Cider vinegar
- Adds acidity that gives the relish its sharp flavour and helps preserve it.
- Brown sugar
- Adds sweetness and depth that balances the sharpness of the vinegar.
- Cabbage
- Adds texture and body to the relish after cooking.
- Onions
- Contributes savoury aroma and flavour to the mixed vegetables.
The step that matters
Press out the surplus juice. Salting and pressing draw out excess water from the vegetables. If too much juice remains, the relish will be watery and may not set well in the jars.
Swap the mango
How well each one fits the dish's main ingredients (tomato, mustard, celery, cider, vinegar, cabbage, onion):
- Avocadofits better
- Limefits better
- Plumfits about as well
- Mangothe original
