Pickled onions are a delicious addition to many dishes! To make them, you'll typically need red onions, vinegar (like white or apple cider), sugar, and salt. Slice the onions, then boil your vinegar with sugar and salt to dissolve. Pour the hot liquid over the onions in a jar, and let them sit in the fridge for a few hours or overnight. Have you made pickled onions before, or is this your first time experimenting with them? How do you plan to use them in your meals?
