Prepare the vegetables. Make sure your veggies are fully rinsed and clean before moving forward.
Make the brining liquid. Combine all the ingredients for your brining liquid in a large pot and bring to a boil. Once the brining liquid is boiling, add your veggies and remove from the heat. The residual heat will par-cook the veggies, but not fully cook them. Allow everything to cool to room temperature.
2 cups white vinegar, 1 cup water, 1 Tablespoon Kosher salt, 1 Tablespoon sugar, 2 teaspoons pickling spice
Brine the vegetables. Once at room temperature, spoon your veggies into a lidded glass jar, then pour the brining liquid over it. Place in your refrigerator and allow to brine for 48 hours.
1 cup cauliflower florets, 1 cup carrot slices, ½ cup white onion, ½ cup celery, ½ cup red bell pepper, ½ cup jalapeños, 1-2 cloves garlic
Serve and enjoy. After your giardiniera brines for a full 2 days, it’s ready to enjoy. Use as a condiment for sandwiches, pastas, salads, and more. Store in your refrigerator for up to 2 months.
