 Ingredients
- 4 cups mixed bell peppers (red, yellow, orange, or green), thinly sliced
- 2 large onions, thinly sliced (yellow or red onions work best)
- 1 cup white vinegar
- 1 cup apple cider vinegar
- 1 cup granulated sugar
- 1 tablespoon mustard seeds
- 1 teaspoon celery seeds
- 1 teaspoon turmeric powder
- 1 teaspoon salt
- 1/2 teaspoon ground black pepper
- 1/2 teaspoon red pepper flakes (optional, for a kick of heat)
 Instructions
Step 1: Make the Pickling Brine
- In a large saucepan over medium heat, combine the white vinegar, apple cider vinegar, sugar, mustard seeds, celery seeds, turmeric, salt, black pepper, and red pepper flakes (if using).
- Stir occasionally until the sugar dissolves completely and the mixture comes to a gentle boil.
Step 2: Add the Vegetables
- Add the sliced bell peppers and onions to the saucepan. Stir well to coat the vegetables in the hot brine.
- Reduce the heat to a low simmer and cook for 10–15 minutes, stirring occasionally. The peppers and onions should soften slightly but still keep some crunch for texture.
Step 3: Cool and Store
- Remove the saucepan from the heat and let the relish cool to room temperature.
- Carefully spoon the relish (with its brine) into clean, sterilized jars with airtight lids.
- Seal tightly and place in the refrigerator.
- Let the relish chill for at least 24 hours before serving to allow the flavors to meld.
 Storage Tips
- This relish is refrigerator-stable for up to 2 weeks.
- Always use clean utensils when serving to maintain freshness.
- For longer shelf life, it can be water-bath canned—let me know if you’d like instructions for that!
 Serving Suggestions
- Use as a burger or hot dog topping for a colorful, tangy crunch.
- Pair with grilled chicken, sausages, or steaks as a zesty side.
- Spoon over sandwiches, wraps, or tacos to elevate the flavor.
- Stir into potato salad or pasta salad for an unexpected twist.

 Tips and Variations
- Color Tip: Use a mix of red, yellow, and orange bell peppers for a gorgeous, vibrant relish.
- Add more heat: Increase the red pepper flakes or add a chopped jalapeño to the brine.
- Sweeter version: Add an extra 1–2 tablespoons of sugar for a sweeter, bread-and-butter-style relish.
