Dickinson’s Sweet ‘N Hot Pepper and Onion Relish transforms humble ingredients into a vinegar-braised spice bomb that elevates every charcuterie board or sandwich spread. This recipe delivers the perfect balance of sweetness and heat, with tender onions and peppers simmered in a tangy, aromatic broth that clings to every bite.

I first discovered this technique while perfecting my homemade relishes, and it quickly became a staple in my kitchen—especially when paired with sharp cheddar or crispy pork belly.

The beauty of this relish lies in its versatility and depth of flavor. Sweet bell peppers and onions caramelize slowly in vinegar, creating a glossy, jam-like texture that’s both sweet and tangy, with just enough cayenne to add a subtle kick.

Unlike store-bought versions, this recipe develops rich, complex notes from simmering spices and fresh herbs, making it far more dynamic. The process is straightforward but requires patience—letting the mixture reduce for 30 minutes ensures the flavors meld perfectly.

What you’ll end up with is a glossy, spiced relish that’s ideal for drizzling over charcuterie, spreading on burgers, or pairing with sharp cheeses. The sweetness of the peppers and onions balances the acidity of the vinegar, while the cayenne adds a lingering warmth that lingers on the palate.

This isn’t just a condiment—it’s a flavor enhancer that turns simple dishes into standout meals. Ready to make it? Here’s everything you need.

Once complete, this relish keeps well in the refrigerator for up to 3 months, making it perfect for gifting or meal prepping. For a longer shelf life, you can even can it in small jars—just follow standard water-bath canning procedures.

Ingredients for dickinson’s sweet n hot pepper and onion relish

Ten simple ingredients transform into a vibrant, tangy-sweet relish perfect for charcuterie or sandwiches.

The onions and sweet bell peppers are the heart of this relish. Yellow onions add depth while red or yellow bell peppers bring natural sweetness—Trader Joe’s has great prices for organic varieties. For the best flavor, look for firm, unblemished peppers and onions with crisp whites. I usually grab these from the produce section at Whole Foods when they’re on sale, but any grocery store’s fresh produce aisle works. The vinegar should be white or apple cider—Bragg’s is my go-to for consistent quality, but any good-quality vinegar will work. The sugar helps balance the acidity, so don’t skip it, but brown sugar adds subtle caramel notes if you prefer a deeper flavor.

No cayenne pepper? Red pepper flakes at half the amount works in a pinch, but you’ll lose some of that smooth heat. Fresh thyme is ideal, but dried thyme at one-third the amount gets you close. If you’re short on garlic, garlic powder at double the amount is fine, though fresh is always better. For the vinegar, white wine vinegar adds complexity if you want to experiment. The olive oil at the end is key—it gives that glossy finish and helps the relish cling to everything. If you’re making this for a crowd, double the batch—it keeps beautifully in the fridge.

This relish tastes even better after 24 hours as the flavors meld. Store in an airtight container in the fridge for up to 3 months. For gifting, transfer to small jars—Ball jars are perfect and make beautiful presents. If you’re canning, follow standard water-bath canning procedures for shelf-stable storage. The relish thickens as it cools, so it’s perfect for drizzling or spreading. Leftovers? Use within 2 weeks for peak freshness.

Step-by-step instructions for sweet ‘n hot pepper and onion relish

Here’s the method—simple but precise—to create that signature tangy, spicy-sweet relish perfect for charcuterie boards.

In a large, heavy-bottomed pot, heat the 1 tablespoon extra-virgin olive oil over medium-high heat. Add the 2 cups medium-diced yellow onions and 2 cups finely chopped sweet bell peppers, stirring occasionally for 8-10 minutes until the onions soften and the peppers begin to release their juices. You’ll know they’re ready when the onions turn translucent and the peppers start to collapse slightly.

Here’s the thing—don’t rush this step. The vegetables need to develop flavor and release their natural sugars through slow cooking. If they stick, add a splash of water and scrape the bottom with a wooden spoon to prevent burning. This is where the foundation of your relish’s depth begins.

Once the vegetables are softened, reduce the heat to medium and add the 3 minced garlic cloves, 1 tablespoon fresh thyme leaves, 1 teaspoon cayenne pepper, 1 teaspoon ground black pepper, and 1.5 teaspoons salt. Stir everything together and let it cook for 2-3 minutes until the garlic becomes fragrant and the spices bloom. You’ll notice the kitchen fill with a warm, earthy aroma—this is your cue that the aromatics are ready.

I always press down gently on the vegetables with a wooden spoon during this time. This ensures the garlic and thyme infuse properly into the mixture, creating layers of flavor that will carry through the entire relish. If the mixture starts to stick, add another splash of water—just enough to keep it moist but not watery.

Pour in the 1.5 cups white vinegar and 0.75 cup granulated sugar, stirring well to combine. Increase the heat to medium-high and bring the mixture to a gentle boil. Once boiling, reduce the heat to low and let it simmer uncovered for 30-40 minutes, stirring occasionally. The relish will thicken as it cooks, and you’ll see a glossy sheen develop on the surface—this is the sign of a properly braised relish.

During this time, the vinegar will mellow out, and the sugar will caramelize slightly, balancing the heat from the cayenne. Taste the relish after 20 minutes—if it needs more sweetness or heat, adjust with additional sugar or cayenne. The goal is a perfect harmony between tangy, sweet, and spicy. Real talk: this is the moment that matters, so don’t walk away.

After simmering, increase the heat to medium and let the relish reduce for an additional 5-10 minutes until it reaches your desired thickness. It should coat the back of a spoon but still be spreadable. If it’s too thick, add a splash of water or vinegar to loosen it.

For that signature glossy finish, drizzle in the remaining 1 tablespoon extra-virgin olive oil and stir gently. This not only adds richness but also helps the relish hold its shape when served. Let it cool to room temperature—this allows the flavors to meld even further. Your relish is now ready to elevate any charcuterie board, sandwich, or cheese platter.

Pro cooking tips for perfect results

Control the Heat

Cayenne pepper delivers the signature kick, but balance is key. Start with 1 teaspoon and taste after simmering. For milder heat, reduce to ½ teaspoon or swap for ½ teaspoon red pepper flakes—they add color but less smooth heat.

If you prefer a smoky depth, add ¼ teaspoon smoked paprika alongside the cayenne. 🌶️

Master the Simmer

Simmering at low heat for 30-40 minutes transforms this relish from ordinary to extraordinary. The vinegar mellows while the sugar caramelizes, creating that perfect sweet-tangy balance. I use a heavy-bottomed pot (like All-Clad) to prevent scorching—this ensures even heat distribution.

Stir occasionally to prevent sticking, but avoid constant stirring, which can break down the vegetables too quickly.

Adjust the Thickness

The ideal consistency coats the back of a spoon but remains spreadable. If your relish is too thick after simmering, add 1-2 tablespoons vinegar or water and reduce again.

For extra gloss, finish with 1 tablespoon olive oil—this not only adds richness but also helps the relish cling beautifully to charcuterie or sandwiches. If it’s too thin, simmer uncovered for an additional 5-10 minutes to thicken naturally.

Flavor Boosting Tips

Add 1 teaspoon soy sauce during the simmer for an umami depth that elevates the relish to restaurant-quality levels. Or, for a fruity twist, stir in 1 teaspoon orange zest with the sugar—it brightens the flavors beautifully.

Fresh herbs like parsley or basil added at the end provide a vibrant finish. Honestly, these small tweaks can turn a good relish into a great one.

Prevent Graininess

To avoid a gritty texture, chop the onions and peppers uniformly—aim for medium dice (about ¼-inch pieces). Pulse them briefly in a food processor if needed, but don’t over-blend.

Also, strain the mixture through a fine-mesh sieve after simmering if you prefer a smoother consistency. This step is especially useful if you’re using thicker-skinned onions or tougher pepper varieties.

Storage Secrets

Let the relish cool completely before transferring to an airtight container. It keeps for up to 3 months in the fridge, with flavors deepening over time. For gifting, use small Ball jars—they’re microwave-safe and add a rustic touch.

If canning, process in a water bath for 10 minutes to ensure shelf stability. The relish thickens as it cools, so store it at room temperature for easier spreading when ready to use. ✨
