How to "pickle" jalapeños, no canning required, all it takes is five minutes and five ingredients and you'll have these cute little rings of pickled jalapeños. These are "quick" pickles, that means they're kept in the refrigerator and still keep for weeks, even months. And lucky day, that means the jalapeños are always on hand for tacos, nachos or wherever you usually pile on some jalapeños. Better still? Use pickled jalapeños a few rings at a time, whenever a recipe calls for a bit of minced fresh jalapeño. Budget-Friendly Mexican Meal Prep. Real Food, Fresh & Flexible. Weight Watchers Friendly.
