Ingredient Breakdown: What You’ll Need and Why

Understanding the role of each ingredient helps ensure the best possible flavor and texture in your finished relish.

The Bell Peppers

Red, green, and yellow bell peppers, all finely chopped, form the colorful, crunchy base of this relish. Using a combination of colors not only creates a beautiful visual effect but also offers subtle flavor variation, as red and yellow peppers tend to be slightly sweeter than green peppers.

The Onion and Jalapeño

Sweet onion, finely chopped, adds a mild, slightly sweet allium flavor that complements the peppers beautifully. Jalapeño pepper, seeded and finely chopped, contributes a gentle, background heat without overwhelming the overall sweet-tangy flavor profile of the relish.

The Sugar and Vinegar

Granulated sugar and apple cider vinegar, used in equal amounts, create that classic sweet-and-tangy balance essential to old-fashioned relish. As the mixture simmers, the sugar and vinegar reduce together into a slightly thickened, syrupy liquid that coats every piece of pepper and onion.

The Seasonings

Kosher salt enhances and balances all the other flavors in the relish. Mustard seeds and celery seeds are classic pickling spices that contribute that distinctive, slightly tangy, aromatic flavor found in traditional relishes. Turmeric adds a warm, earthy flavor along with its signature golden color, while freshly ground black pepper rounds out the seasoning with a subtle bite.

The Optional Add-Ins

For those wanting to customize their relish further, options include an additional jalapeño for extra heat, crushed red pepper flakes for a spicier kick, minced garlic for added savory depth, chopped banana peppers for a milder, tangy pepper variety, honey for extra sweetness, and smoked paprika for a subtle smoky dimension.

Step-by-Step Directions

Step 1: Prepare the Peppers

Wash all the peppers thoroughly and remove the stems, seeds, and membranes from the bell peppers and jalapeño.

Step 2: Chop the Vegetables

Finely chop the bell peppers, jalapeño, and sweet onion. For a finer relish texture, you can pulse the vegetables briefly in a food processor, being very careful not to over-process them into a purée — the goal is small, distinct pieces rather than a smooth mixture.

Step 3: Combine in the Saucepan

Transfer the chopped vegetables to a large saucepan. Add the granulated sugar, apple cider vinegar, kosher salt, mustard seeds, celery seeds, turmeric, and black pepper. Stir everything together until well combined.

Step 4: Bring to a Boil

Place the saucepan over medium-high heat and bring the mixture to a gentle boil, stirring occasionally to prevent sticking or scorching.

Step 5: Simmer

Reduce the heat to medium-low and simmer the mixture uncovered for about 20 to 30 minutes, stirring occasionally. Continue simmering until the peppers are tender but still retain a little bit of texture, and the liquid has reduced into a thick, sweet, and tangy relish consistency.

Step 6: Taste and Adjust

Taste the relish carefully and adjust the sweetness, acidity, or heat level as desired, adding any of the optional add-ins at this stage if you’d like to customize the flavor further.

Step 7: Cool Slightly

Remove the saucepan from the heat and allow the relish to cool slightly before transferring it to storage containers.

Step 8: Transfer to Jars

Transfer the finished pepper relish into clean jars or airtight containers.

Step 9: Chill

Once cooled, refrigerate the relish for several hours before serving. This resting period allows the sweet, tangy, and spicy flavors to fully develop and meld together.

Step 10: Serve

Serve this Old-Fashioned Pepper Relish over hot dogs, hamburgers, sausages, sandwiches, grilled chicken, pork, beans, or alongside cheese and crackers.

Expert Tips for the Best Old-Fashioned Pepper Relish

Finely chop rather than purée the vegetables. This is the key to achieving that classic old-fashioned relish texture. You want small, colorful pieces of pepper and onion in every spoonful, not a smooth, blended mixture.

Don’t rush the simmering process. Allowing the mixture to simmer for the full 20 to 30 minutes ensures the liquid reduces properly into a thick, cohesive relish rather than remaining thin and watery.

Taste and adjust before jarring. Since sweetness, acidity, and heat preferences vary from person to person, take the time to taste the relish before transferring it to jars, adjusting with any of the optional add-ins as needed.

Let the relish chill before serving. While it’s tempting to dig in right away, allowing the relish to chill for several hours in the refrigerator gives the flavors time to fully develop and meld together for the best possible taste.

Use a food processor carefully, if using one. Pulsing the vegetables briefly can help achieve a finer, more uniform chop, but be careful not to over-process, as this can turn the relish into more of a sauce than a proper relish.

Adjust the heat level to your preference. Starting with just one jalapeño keeps the base recipe relatively mild, making it easy to build up the heat gradually with additional jalapeño, red pepper flakes, or banana peppers if desired.

Store in clean, airtight jars. Using clean jars and keeping the relish properly refrigerated helps preserve its freshness and flavor for as long as possible.

Frequently Asked Questions

Can I can this relish for long-term storage? This particular recipe is formulated for refrigerator storage. If you’d like to can it for shelf-stable, long-term storage, be sure to follow a tested canning recipe and proper water bath canning procedures to ensure food safety.

How long does this relish keep in the refrigerator? When stored in a clean, airtight container in the refrigerator, this relish typically keeps well for several weeks to a couple of months, though quality is best when used within the first few weeks.
