Ingredients

• 2 cups cauliflower florets (fresh and bite-sized)
• 1 cup carrot slices (thin rounds or sticks)
• 1 cup celery stalks (sliced)
• 1 cup bell peppers (red and green, chopped)
• 1 cup green olives (pitted and halved)
• 3-4 cloves garlic (thinly sliced)
• 1-2 jalapeños (sliced, optional for heat)
• 1 tablespoon black peppercorns
• 1 tablespoon dried oregano
• 2 tablespoons kosher salt (for brine)
• 4 cups filtered water (for brine)
• 2 tablespoons red chili flakes (adjust to taste)
• Fresh parsley (a handful, chopped)

Equipment

• 1 large glass fermentation jar or crock (at least 1 quart)
• Fermentation weight or small glass jar (to keep vegetables submerged)
• Clean kitchen towel or airlock lid
• Mixing bowl
• Measuring cups and spoons
• Sharp knife and cutting board
• Non-metallic spoon for stirring

Instructions

1. Prepare the brine: Dissolve the kosher salt in 4 cups of filtered water. Stir well until fully dissolved and set aside.
2. Chop the vegetables: Wash all vegetables thoroughly. Cut the cauliflower into small florets, slice carrots and celery into thin pieces, chop the bell peppers, and slice the jalapeños if using. Halve the olives and thinly slice the garlic.
3. Combine ingredients in a bowl: Place all chopped vegetables, olives, garlic, black peppercorns, red chili flakes, and dried oregano into a large mixing bowl. Toss gently to mix evenly.
4. Pack the jar: Transfer the mixed vegetables into your fermentation jar, pressing down firmly to remove air pockets. Leave at least 1-2 inches of headspace at the top of the jar.
5. Add the brine: Pour the prepared brine over the vegetables until they are completely submerged. Use a fermentation weight or a smaller glass jar to keep the vegetables beneath the brine to prevent mold formation.
6. Cover and ferment: Cover the jar loosely with a clean kitchen towel secured with a rubber band, or use an airlock lid if you have one. Place the jar in a cool, dark spot (around 65-75°F) and let it ferment for 5 to 14 days.
7. Check daily: Check your giardiniera each day to ensure vegetables remain submerged and skim off any surface scum if needed. Taste test after 5 days to see if the flavor and tang are to your liking. You can ferment longer for a stronger sour taste.
8. Finish and store: Once fermentation is complete, add chopped fresh parsley for brightness. Seal the jar with a lid and refrigerate. The giardiniera will continue to develop flavor in the fridge and can be kept for up to 3 months.

Tips & Variations

“Always use non-iodized salt for fermentation, such as kosher or sea salt, to ensure successful fermentation.”

Feel free to experiment with vegetables! Try adding sliced radishes, green beans, or cherry tomatoes for unique twists.

If you prefer less heat, omit the jalapeños and chili flakes or swap them for milder peppers.

To speed up fermentation, keep your jar in a warmer spot but avoid temperatures above 80°F. Conversely, cooler temperatures slow fermentation, allowing for more nuanced flavor development.

If you want a crisper texture, soak vegetables in ice water for 15 minutes before packing them into the jar. This helps maintain crunch during fermentation.
