• 1/2 teaspoon black pepper
• 1/2 teaspoon ground nutmeg

Shopping List

• Produce: 10-12 medium zucchinis, 4 large yellow onions, 2 large red bell peppers, 2 large green bell peppers
• Pantry: 1 bottle white vinegar (5% acidity), 1 bag granulated sugar, Mustard seeds, Celery seeds, Ground turmeric, Ground nutmeg, Black pepper
• Baking & Spices: Canning salt or kosher salt

Equipment Needed

• Large stainless steel or non-reactive pot
• Measuring cups and spoons
• Wooden spoon or silicone spatula
• 6 clean pint-sized canning jars with lids and bands
• Canning funnel and bubble remover

Helpful Tips

• For the ultimate crisp texture, do not skip the salting and draining process, as drawing out the moisture keeps the relish beautifully crunchy instead of soggy.
• Feel free to customize the heat by substituting some of the sweet bell peppers with finely diced jalapeños, serranos, or even a pinch of red pepper flakes.
• Always opt for non-reactive cookware, such as high-quality stainless steel or enamel-coated pots, to prevent any metallic off-flavors when simmering vinegar.
• Allow the flavors to mature in a dark pantry for at least a week or two before opening, which lets the spices meld into a much deeper flavor profile.

Step-by-Step Instructions

1. Combine the finely chopped zucchini, onions, red bell peppers, and green bell peppers in a large bowl. Sprinkle the canning salt evenly over the mixture and toss well to combine.
2. Let the salted vegetable mixture sit at room temperature for 4 hours (or cover and refrigerate overnight) to draw out excess moisture and ensure the relish stays crunchy.
3. Transfer the vegetables to a colander and rinse thoroughly under cold running water to remove the excess salt. Let drain completely, then use your hands or a clean kitchen towel to squeeze out as much remaining liquid as possible.
4. In a large, non-reactive pot, combine the white vinegar, granulated sugar, mustard seeds, celery seeds, ground turmeric, black pepper, and nutmeg. Bring the mixture to a boil over medium-high heat, stirring until the sugar is fully dissolved.
5. Add the drained vegetables to the boiling syrup. Stir well to combine, bring the mixture back to a boil, then reduce the heat to medium-low and simmer uncovered for 30 minutes, stirring occasionally, until the relish thickens slightly.
6. For immediate use, let the relish cool completely, transfer to clean jars, and store in the refrigerator for up to 3 weeks. For long-term preservation, ladle the hot relish into sterilized hot pint jars leaving 1/2-inch headspace, and process in a boiling water bath canner for 15 minutes.

Variations & Serving Ideas

Elevate your backyard dining experience by spooning this zesty relish over freshly grilled burgers, charred sausages, or classic hot dogs.
