Pickled Red Onions Tips

What is the best vinegar to use for pickling?

White vinegar is commonly used in pickling recipes. This pickled red onion recipe calls for white wine vinegar or cider vinegar, and whichever one you have on hand will work well. If you don't have either, white vinegar is a suitable substitute. One vinegar that you won't want to use when pickling is balsamic vinegar—save that for salad dressings, marinades and finishing dishes. Check out our other pickled recipes for inspiration. And, learn how to pickle safely.

What are some variations of this pickled red onions recipe?
