This slightly spicy, crunchy and tangy relish will keep in the refrigerator for a month, but we're betting you'll use it up long before. Serve it as a condiment with everything from fried chicken-and-biscuits to fried rice, fold it into egg or chicken salad, or use it like giardiniera, layered with meat and cheeses on a crusty roll. And if you have some on hand...Stir some mustard seeds into the pickling liquid for a little extra crunch and flavor.
Trim the skinny tops and dark green leaves from the celery and discard or save them for soup. Save a handful of tender, light green leaves from the heart. Slice the ribs about 1/8-inch thick on an angle. Put the celery pieces and light green leaves in a large nonreactive bowl.
In a medium saucepan, bring the vinegar, 1 cup water, the sugar, salt, ginger and chile to a boil, stirring once or twice. Pour over the celery. Transfer to a mason jar or any sealable container, using a spoon or fork to press the celery into the liquid. Cover and refrigerate (it's okay if the mixture is still slightly warm) at least overnight before eating (the pickles will keep, refrigerated, for up to 1 month).
