Ingredients
3 cups grated zucchini (about 2–3 medium zucchinis)
3 cups chopped red or green pepper (about 2–3 whole peppers)
1 cup grated onion (about 1 large onion)
2 cups apple cider vinegar, divided
1 cup white sugar
1 tablespoon salt (not iodized)
1 tablespoon yellow mustard seeds
1/2 teaspoon celery seed
Pinch of red pepper flakes (optional)
Instructions
- Fill a water bath canner or large stockpot with water and bring to a boil. Wash 5 half-pint jars, lids, and rings in hot soapy water. Place jars in the water bath to heat and set aside lids and rings.
- In a large non-reactive pot, combine zucchini, pepper, and onion. Stir in 1 cup apple cider vinegar and bring to a simmer over medium heat. Cook for about 30 minutes until vegetables soften.
- Drain any excess vinegar and add remaining apple cider vinegar, sugar, salt, mustard seeds, celery seed, and red pepper flakes (if using). Bring back to a simmer and cook for 5 minutes.
- Ladle hot relish into heated jars, leaving 0.5 inch (12mm) headspace. Remove air bubbles, wipe rims clean, place lids, and screw on rings fingertip tight.
- Place jars in the water bath and process for 10 minutes. Turn off heat, remove lid, and let jars sit for 5 minutes before removing. Let jars sit undisturbed overnight.
- The next day, remove rings, check seals, wipe jars, label, and store in a cool, dark place.
Notes
- For a spicier relish, add more red pepper flakes or a chopped jalapeƱo.
- You can substitute apple cider vinegar with white wine or rice vinegar for a different flavor.
- For a sugar-free version, replace white sugar with a sugar alternative like stevia or monk fruit.
- Properly sealed jars can last up to a year when stored in a cool, dark place.
