5 cups ground green bell peppers (About 7 to 8 peppers, or 3 to 4 pounds before grinding)
5 cups ground red bell peppers (About 7 to 8 peppers, or 3 to 4 pounds before grinding)
1-½ cups ground onion (3 medium yellow onions, 2.5 to 3 inches diameter, before grinding)
2-½ cups cider or white distilled vinegar (5%)
2 cups sugar
4 teaspoons pickling salt
4 teaspoons mustard seed
Wash and rinse pint or half-pint canning jars; keep hot until ready to fill. Prepare lids and ring bands according to manufacturer’s directions.
Wash peppers well; trim to remove stems and seeds. Peel, core and wash onions. Cut peppers and onions into large pieces. Coarsely grind peppers and onions (see Note at end of procedure).
Measure 5 cups of each type of ground bell peppers with their juice, and 1-½ cups of the ground onion, including juice. Combine the measured peppers and onions with the remaining ingredients into a large stockpot. Bring the mixture to a boil over high heat. Reduce heat and cook at a low boil for 30 minutes, stirring often to prevent scorching.
Fill the hot relish into prepared hot pint jars, leaving ½-inch headspace. If needed, remove air bubbles and re-adjust headspace to ½-inch. Wipe rims of jars with a dampened clean paper towel. Adjust lids and bands.
Process in a boiling water canner. Let cool, undisturbed, 12 to 24 hours and check for seals.
Yield: About 6 pint jars
