Bay Area Bites has a super-sweet recipe for pickled jalapeños, which are vegan by default and also one of the world’s greatest foods. Not just sour, not just salty, but vegetal and SPICY, it is truly wonderful.
Don’t want to bother with canning? You can do this in the fridge! Refrigerator-pickled produce is a simple and easy way of preserving food you have no intention of letting sit around longer than a week, because it is too delicious to wait for.
