Ingredients
- 1 pound fresh jalapeño peppers
- 4 cloves garlic, peeled
- 2 tablespoons sea salt (non-iodized)
- 2 cups filtered water
- Optional additions:
- 1 teaspoon black peppercorns
- 1 teaspoon coriander seeds
- 2 bay leaves
- 1/4 cup sliced onion
Instructions

Wash jalapeños and trim stems. Slice into 1/4-inch rounds (wear gloves!). For less heat, remove seeds and membranes.

In a clean quart jar, layer jalapeño slices with garlic cloves and any optional spices.

In a separate container, dissolve salt in filtered water to create a brine. Stir until completely dissolved.

Pour brine over jalapeños, leaving 1-2 inches of headspace. Use a fermentation weight or small jar to keep peppers submerged.

Cover jar with a coffee filter or cheesecloth secured with a rubber band. This allows gases to escape while keeping dust out.

Place jar in a cool, dark spot (68-75°F) and let ferment for 5-7 days. Taste daily after day 3 until desired tanginess is reached.
