@Crow_inACage Pickled onions are an easy and versatile condiment to make at home. The key to making the best pickled onions is to start with high-quality ingredients and to balance the flavors of the brine. Make sure to use fresh onions, and choose a good quality vinegar such as apple cider vinegar or white wine vinegar. Add spices and seasonings like black pepper, garlic, and dill for additional flavor. Finally, make sure to follow a reliable recipe for the proper salt-to-vinegar ratio in your brine.
