yields about 10 half-pint jars
6 cups/890 g chopped green bell pepper (about 6 whole peppers)
6 cups grated green or a mix of green & yellow zucchini (about 2 ½ -3 pounds zucchini)
2½ cups grated onion (about 2 large onions)
4 cups/960 ml apple cider vinegar, divided
2 cups/400 g granulated sugar
2 Tablespoons sea salt
2 Tablespoons mustard seed
1 teaspoon celery seed
½ teaspoon red pepper flakes
- Sterilize five 1-pint or 10 half-pint jars. Prepare a waterbath for canning.
- Combine the chopped bell pepper, zucchini, and onion in a large, nonreactive pot. Stir in 2 cups/480 ml of the apple cider vinegar and bring to a simmer over medium heat. Cook until the vegetables have cooked down, about 30 minutes.
- Drain the vegetables and return them to the pot. Add the remaining 2 cups apple cider vinegar, plus the sugar, salt, mustard seed, celery seed, and red pepper flakes. Bring to a simmer and cook for 5 minutes.
- Ladle the relish into the prepared jars, leaving 1/2 inch/12 mm of headspace. Gently tap the jars on a towel-lined countertop to help loosen any bubbles before using a wooden chopstick to dislodge any remaining bubbles. Wipe the rims, apply the lids and rings, and process in a boiling water bath for 10 minutes.
- When the processing time is up, remove the canning pot from the flame and remove the lid from the pot. Let the jars sit in the pot for an additional 5-minutes. This helps to prevent the relish from reacting to the rapid temperature change and bubbling out of the jars.
