Pickled Turnips are a delicious way to highlight the earthy and sweet flavor, as well as the crisp texture, of a turnip. These tangy roots make for a wonderful pickled veggie option and are an excellent addition to any savory plant-based dish that needs a bit of tang and crunch.
Add the turnips, garlic, shallots, and black peppercorns, if using, to a 32-ounce mason jar (or equivalent glass jar).
Add the water, vinegar, mustard seeds, bay leaf, sugar (if using), and salt to a medium stovetop pot. Bring to a boil and let simmer for 5 minutes. Set aside to cool.
Transfer the brine to the mason jar. Shake well and make sure the turnips are fully submerged in the brine.
Refrigerate for at least 2 days before serving.
