Homemade pickled jalapeños are sliced fresh jalapeños packed into sterilized jars and covered with a boiling brine of white vinegar, water, sugar, salt, pepper, and coriander seeds, then cooled upside down and left in the refrigerator for 3 days before eating. They take 10 minutes of cooking plus 3 days of resting and make 6 servings.
They are a simple, versatile condiment for salads, meats, sandwiches, and empanadas, perfect if you like spicy food.
How to Make Pickled Jalapeños?
Choose large, firm jalapeños so the slices keep the crunch of the raw chili. The brine is brought to a boil and poured over the peppers, and the jars are sealed and chilled.

Additional Tips
Pick firm peppers
Large, firm jalapeños keep their crunch best after pickling.
Keep the acidity
You can use apple cider or rice vinegar, but keep the vinegar-to-water ratio so the pickles stay safe.
Handle with gloves
Wear gloves when slicing jalapeños and avoid touching your eyes, since capsaicin irritates the skin.
