Ingredients

Scale

This recipe uses a simple list of fresh vegetables and pantry spices to recreate that classic deli relish flavor. Here’s what you’ll need:

- 3 cups cucumbers, finely diced
- 1 cup green bell pepper, finely diced
- 1/2 cup red bell pepper, finely diced

- 1 small onion, finely diced
- 1 cup white vinegar
- 1/2 cup granulated sugar

- 1 tablespoon pickling salt or kosher salt
- 1 teaspoon mustard seeds
- 1/2 teaspoon celery seeds

- 1/2 teaspoon turmeric
- 1/2 teaspoon black pepper
- 2 cloves garlic, minced

Each component plays an important role in the final flavor and texture. The cucumbers form the base of the relish, providing that classic crunch, while the bell peppers add sweetness and a pop of color. The onion brings a savory bite, and the vinegar and sugar create the tangy-sweet brine that defines deli-style relish. The mustard seeds, celery seeds, turmeric, and black pepper round out the flavor with warm, slightly earthy spice notes, while the turmeric also gives the relish its signature golden-yellow hue.

Instructions

Step 1: Salt and Drain the Vegetables

In a large bowl, combine the finely diced cucumbers, green bell pepper, red bell pepper, onion, and pickling salt. Toss everything together well and let the mixture sit for about an hour. This step draws excess moisture out of the vegetables, which is the secret to achieving that signature crunchy relish texture instead of a watery, diluted final product.

Step 2: Drain and Squeeze

After the vegetables have had time to release their liquid, drain them thoroughly in a colander. Then, gently squeeze out any remaining excess moisture using a clean kitchen towel or cheesecloth. This step is important, since any leftover water can thin out your brine and affect the final consistency of the relish.

Step 3: Make the Brine

In a saucepan, combine the white vinegar, granulated sugar, mustard seeds, celery seeds, turmeric, black pepper, and minced garlic. Bring the mixture to a gentle simmer over medium heat, stirring occasionally until the sugar has fully dissolved into the brine.

Step 4: Cook the Vegetables in the Brine

Add the drained vegetables to the saucepan with the brine and let everything simmer together for 8 to 10 minutes, stirring occasionally. This brief cooking time allows the vegetables to absorb the tangy, spiced flavor of the brine while still retaining their crunch.

Step 5: Cool Slightly

Once the relish has finished simmering, remove the saucepan from the heat and let it cool slightly before transferring it to jars. This helps prevent excess condensation from forming inside the jars once sealed.

Step 6: Jar and Cool Completely

Transfer the relish into clean glass jars and allow it to cool completely at room temperature before sealing and refrigerating.

Step 7: Chill Before Serving

For the best flavor, refrigerate the relish overnight before serving, which allows the flavors to fully meld together. If you’d prefer a shelf-stable relish for long-term storage, you can process the jars in a water bath according to safe, tested canning guidelines.
