Ingredients
- 10-12 fresh jalapeños (about 1 lb), sliced into 1/4-inch rounds
- 1 cup white vinegar (5% acidity)
- 1 cup water
- 2 tbsp granulated sugar (or honey)
- 1 tbsp kosher salt
- 2 garlic cloves, peeled and smashed
- 1 tsp black peppercorns
- 1 tsp mustard seeds (optional, for extra flavor)
- Optional: 1 small carrot, sliced, or 1/4 onion, sliced (for color and flavor)
- Optional: 1 bay leaf or 1/2 tsp oregano (for herbaceous notes)
Step-by-Step Process
- Prepare Jalapeños: Wash jalapeños and slice into 1/4-inch rounds, discarding stems. Wear gloves to avoid skin irritation from capsaicin. Set aside.
- Sterilize Jar: Wash a 1-pint (16 oz) mason jar and lid in hot, soapy water or run through a dishwasher. Optionally, sterilize by boiling for 10 minutes. Let dry.
- Make Brine: In a medium saucepan, combine vinegar, water, sugar, salt, garlic, peppercorns, mustard seeds (if using), and optional bay leaf or oregano. Bring to a boil over medium heat, stirring until sugar and salt dissolve, about 2-3 minutes.
- Pack Jar: Place jalapeño slices and optional carrot or onion in the jar, packing tightly but leaving 1/2-inch headspace. Pour hot brine over the vegetables, ensuring they’re fully submerged. Use a clean spoon to press down and remove air bubbles.
- Cool and Seal: Let the jar cool to room temperature, about 1 hour. Seal with the lid and refrigerate for at least 4 hours (preferably 24 hours) to develop flavors.
- Serve or Store: Serve as a condiment on tacos, sandwiches, or salads. Store in the fridge for up to 1 month.
Tips for Better Pickled Jalapeños
- Choose firm, glossy jalapeños for crisp pickles; avoid soft or wrinkled ones.
- Adjust sugar to balance heat; reduce to 1 tbsp for less sweetness.
- Wear gloves when slicing jalapeños to prevent skin or eye irritation.
- Submerge jalapeños fully in brine to prevent spoilage.
- Let pickles sit for 24-48 hours for optimal flavor infusion.
- Sterilize jars thoroughly to extend shelf life in the fridge.
- Taste the brine before pouring; adjust salt or vinegar for preference.
- Use a clean utensil to remove the pickles to avoid contamination.
Variations and Customization
- Spicy Pickled Jalapeños: Add 1-2 sliced serrano peppers or 1/4 tsp red pepper flakes.
- Mild Pickled Jalapeños: Remove seeds and membranes before slicing.
- Sweet Pickled Jalapeños: Increase sugar to 1/4 cup for a candied effect.
- Garlic Pickled Jalapeños: Add 2 extra garlic cloves or 1 tsp garlic powder.
- Pickled Mixed Veggies: Include 1/2 cup cauliflower florets or bell pepper slices.
- Smoky Pickled Jalapeños: Add 1/2 tsp smoked paprika or a chipotle pepper.
- Vinegar Variations: Swap white vinegar for apple cider vinegar or rice vinegar.
- Low-Sodium Pickled Jalapeños: Reduce salt to 1 tsp and use low-sodium vinegar.
Storage and Serving Tips
- Store in an airtight jar in the fridge for up to 1 month; flavors deepen over time.
- Do not freeze, as jalapeños lose crispness; freezing also risks jar cracking.
- Serve on nachos, pizza, scrambled eggs, or as a Bloody Mary garnish.
- Use leftovers in quesadillas, chili, or blend into a spicy aioli.
- Check for spoilage (cloudy brine, off smells) before consuming.
- Keep the jar sealed when not in use to maintain freshness.
- Avoid leaving at room temperature for more than 2 hours.
- Pair with Mexican dishes, BBQ, or charcuterie boards for a spicy kick.
