Mixing Bowl: A must for combining your veggies and ensuring they soak in the delicious flavors of the hot mixture.
Storage Containers: Glass jars or plastic containers will keep your relish fresh and ready to share or enjoy later.

Ingredients for Sweet & Tangy Old-Fashioned Pepper & Onion Relish

2 cups bell peppers, chopped: Bright, aromatic, and slightly sweet, bell peppers are the foundation of this relish. Feel free to use a mix of colors—yellow, red, and green—for a vibrant look and varied flavor.
1 cup onions, chopped: A staple in many kitchens, onions add depth and a slight zing that pairs perfectly with the sweetness of the peppers.
1 cup vinegar (white or apple cider): The acidic counterpart, vinegar cuts through the sweetness and balances the relish. Apple cider vinegar provides a subtle fruity note.
1 cup sugar: Sweetness is the star of the show, making the tang of the vinegar all the more pronounced.
1 tablespoon salt: Salt enhances the overall flavor, ensuring every bite is seasoned perfectly.
1 teaspoon black pepper: This simple spice brings a hint of warmth that rounds out the flavors beautifully.
1 teaspoon mustard seeds: A touch of earthiness from the mustard seeds adds a delightful crunch and flavor complexity.
1/2 teaspoon garlic powder: This little ingredient infuses a subtle depth, enhancing the relish’s savory qualities without overpowering it.

If you want to switch up the flavors, consider using different types of onions, like red or sweet Vidalia onions.

How to Make Sweet & Tangy Old-Fashioned Pepper & Onion Relish

In a large bowl, combine the chopped bell peppers and onions. This step allows the vegetables to mingle before they meet their sweet and tangy partner, vinegar.
In a medium saucepan, combine vinegar, sugar, salt, black pepper, mustard seeds, and garlic powder. Stir gently while bringing the mixture to a boil. Keep an eye on it; consistent stirring ensures the sugar dissolves completely, creating a syrupy base.
Once boiling, pour the hot mixture over the peppers and onions in your mixing bowl. The warmth will coax the flavors from your veggies, making them sing with excitement.
Let the relish cool to room temperature before transferring it to storage containers. Refrigerate for several hours or overnight to allow the flavors to meld into a harmonious blend.
Serve this delightful relish as a topping for grilled meats, layered in sandwiches, or as a dip alongside an assortment of crunchy snacks.

Chef’s Notes & Helpful Tips

Make-ahead tips: Prepare your relish a day or two in advance. This allows the flavors to deepen and develops a richer taste.
Cooking alternatives: If you’re short on time, consider using an air fryer to cook your peppers briefly for a crunchy but tender texture, although this may not retain as much liquid for the relish.
Customization ideas: Experiment with adding jalapeños for a spicy kick or crushed pineapple for a tropical twist. Adjust the sugar to suit your desired sweetness level.

Common Mistakes to Avoid

One of the most frequent errors in making this relish is overcooking the vegetables. You want them to remain crunchy and vibrant, which means a gentle simmer is all that’s needed. Additionally, don’t skip the refrigeration time. Allowing the relish to sit lets the flavors meld beautifully. Lastly, make sure your vinegar is fresh—an old bottle can compromise the taste significantly.
