A mexican style jalapeno pickled. Fresh jalapeños are hit or miss if you want either medium-heat or mild peppers. If you are pickling fresh jalapeños at home, note that the pickling process will slightly reduce the heat of fresh peppers. Chopped pickled jalapeños can add a spark and an extra acidic note to your carnitas, salsas, and to your quesadillas. They are great in guacamole, too, especially if you do not have any limes on hand.
