Key Ingredients
Let’s gather everything you need to bring this vibrant relish to life:

- 1 cup apple cider vinegar: The acidic backbone that balances sweetness and preserves the veggies with a gentle tang.
- 1/2 cup water: Dilutes the vinegar slightly, ensuring the brine isn’t too overpowering.
- 1/2 cup granulated sugar: Sweetens the brine to counterbalance the acidity, yielding that signature “sweet and tangy” taste.
- 1 teaspoon kosher salt: Enhances all the flavors and helps draw moisture from the vegetables for better texture.
- 1 teaspoon mustard seeds: Releases a subtle, pungent kick when simmered, contributing depth to the brine.
- 1/2 teaspoon celery seeds: Adds earthy, slightly peppery notes that complement the sweetness of the peppers.
- 1/4 teaspoon crushed red pepper flakes: Provides a mild heat that warms the palate without overwhelming it.

How To Make Sweet and Tangy Pickled Pepper and Onion Relish
Crafting this relish is a breeze—just a few simple steps transform fresh veggies into a tangy, spiced condiment that’ll elevate any meal. You’ll simmer the brine to infuse the spices, then marry it with crisp peppers and onions before chilling to let the flavors meld beautifully.
1. Combine the brine: In a saucepan over medium heat, combine 1 cup apple cider vinegar, 1/2 cup water, 1/2 cup granulated sugar, and 1 teaspoon kosher salt, stirring until the sugar fully dissolves.
2. Spice infusion: Add 1 teaspoon mustard seeds, 1/2 teaspoon celery seeds, 1/4 teaspoon crushed red pepper flakes, and 1 clove garlic, minced to the hot brine, then simmer for 2 minutes to release those essential oils.
3. Prepare the vegetables: Place 2 cups mixed bell peppers, thinly sliced and 1 cup red onion, thinly sliced into a heatproof bowl or jar, layering evenly.
4. Pour the brine: Carefully pour the hot brine mixture over the peppers and onions, using a spoon to stir and ensure even coating of every ribbon.
5. Cool and refrigerate: Let the relish cool to room temperature, then cover and refrigerate for at least 4 hours—overnight is best for peak flavor.
6. Serve: Enjoy your pickle relish chilled or at room temperature as a zesty condiment alongside your favorite dishes.

Tips For Perfect Sweet and Tangy Pickled Pepper and Onion Relish
I always find that tiny tweaks can turn a good recipe into a great one. Keep these friendly pointers in mind next time you whip up this relish to ensure it’s bursting with flavor, texture, and crunch.
- Relish can be stored in an airtight container in the refrigerator for up to 4 weeks, so feel free to batch-make and enjoy throughout the month.
- Adjust sugar and vinegar ratios to dial sweetness or tang up or down—just taste your brine before simmering and tweak one tablespoon at a time.
- For extra crunch, rinse and drain the peppers and onions in a colander before adding the brine to remove surface moisture and prevent steaming.
- Wear gloves when handling hot peppers (if you choose to add them) to protect your skin from capsaicin and avoid any surprise irritation.
How To Store It
Proper storage ensures your relish stays crisp, flavorful, and ready whenever you need a zesty boost. Follow these guidelines to maintain freshness and prevent spoilage:
- Airtight Jar: Transfer the cooled relish into a clean, airtight jar or container to seal in flavor and prevent odors from creeping in.
- Refrigerate Promptly: Store the sealed jar in the coolest part of your refrigerator (usually near the back) to slow down any bacterial growth.
- Use Clean Utensils: Always scoop out relish with a clean, dry spoon—introducing moisture or crumbs can shorten its shelf life.
- Label with Date: Stick a label on the jar with the preparation date so you know it’s best within 4 weeks for top-notch crunch and flavor.
Frequently Asked Questions
Here are a few common questions I get about this relish—let’s clear them up!
- How long does it take to prepare this sweet and tangy pickled pepper and onion relish?
Total active time is about 10–15 minutes. That includes 5–7 minutes to slice the peppers and onions, 2 minutes to simmer the brine mixture, and a few minutes to pour the brine over the vegetables and stir. You’ll then need to allow it to cool and chill (see next question).
- How long should I refrigerate the relish before serving?
Refrigerate for at least 4 hours to let the flavors meld, but overnight (8–12 hours) yields the best balance of sweetness, tang, and aromatic seed flavors. You can serve it chilled or let it come to room temperature before serving.
- How long can I store this relish in the refrigerator?
Stored in an airtight container or jar, it will keep its peak flavor and texture for up to 4 weeks. Always use a clean utensil when scooping it out to prevent contamination.
- What’s the best way to keep the peppers and onions extra crunchy?
Before adding the hot brine, rinse and thoroughly drain the sliced peppers and onions in a colander. This removes excess surface moisture, so the vegetables won’t steam as much under the hot brine and will retain a firmer bite.
- How can I adjust the sweetness or tanginess to suit my taste?
To increase sweetness, add up to 2 extra tablespoons of sugar to the brine, tasting as you go. To boost tanginess, reduce the sugar by 1–2 tablespoons or increase the vinegar by up to 2 tablespoons. Stir well, simmer briefly to dissolve, and proceed with the recipe.
- Can I omit or swap any of the spices in the brine?
Yes. Mustard seeds add a subtle pungent kick, celery seeds bring earthiness, and crushed red pepper flakes lend mild heat. You can omit the crushed red pepper for a milder relish or replace mustard seeds with yellow or brown mustard seeds. Just maintain the total volume of spices so the flavor remains balanced.
- Do I need to wear gloves when handling these peppers and onions?
For standard bell peppers and red onion, gloves aren’t necessary. The recipe note about gloves applies only if you choose to add hot chili peppers to boost heat—capsaicin from hot peppers can irritate skin and eyes if handled without protection.
