## Ingredients

Here’s what you’ll need to make a batch of Pickled Pepper and Onion Relish:

4 cups mixed bell peppers, thinly sliced (use red, yellow, orange, and green for a colorful mix)
2 large onions, thinly sliced (yellow or red onions work well)
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
½ teaspoon ground black pepper

Optional:

½ teaspoon red pepper flakes for a spicy kick
1 clove garlic, minced, for added depth

Instructions

Step 1: Prepare the Vegetables

Wash and dry the bell peppers and onions.
Remove the stems and seeds from the peppers, then slice them thinly.
Peel and thinly slice the onions.
Combine the sliced vegetables in a large mixing bowl and set aside.

Step 2: Make the Pickling Brine

In a large saucepan, combine white vinegar, apple cider vinegar, sugar, mustard seeds, celery seeds, turmeric, salt, and black pepper.
If using garlic or red pepper flakes, add them now.
Bring the mixture to a boil over medium-high heat, stirring until the sugar dissolves completely.

Step 3: Combine and Simmer

Add the sliced peppers and onions to the boiling brine.
Reduce the heat to medium-low and simmer for 10–12 minutes, stirring occasionally.
The vegetables should soften slightly but retain some crunch. Step 4: Sterilize the Jars
While the relish simmers, sterilize your canning jars and lids by boiling them in water for 10 minutes.
This step ensures safe long-term storage.

Step 5: Fill the Jars

Carefully ladle the hot relish into the sterilized jars, leaving about ½ inch of headspace.
Wipe the rims clean, then seal with lids and bands.

Step 6: Process the Jars

Place the filled jars in a boiling water bath for 10 minutes.
Ensure jars are fully submerged and spaced apart.
After processing, remove jars and let them cool on a towel-lined counter.

Step 7: Store and Enjoy

Once cooled, check the seals by pressing the center of each lid.
Store sealed jars in a cool, dark place for up to 1 year.
Refrigerate after opening and use within 1 month.

Tips for Success

Uniform slicing ensures even pickling and a better texture.
Use fresh, firm vegetables for the best flavor and crunch.
Don’t skip the turmeric—it adds color and a subtle earthy note.
Taste the brine before adding vegetables and adjust sugar or vinegar to your preference.

Flavor Variations

Spicy Relish

Add jalapeños or red pepper flakes for heat.

Smoky Relish

Use smoked paprika or chipotle powder for a smoky twist.

Herbed Relish

Add fresh thyme or oregano for a Mediterranean vibe.
