Pickled onions are fantastic on tacos, burgers, and salads. They also work well as a garnish for grilled meats and seafood, adding a tangy crunch that complements rich flavors.

- Not allowing enough marinating time for the flavors to develop.
- Skipping the sugar, which balances the acidity of the vinegar.
- Using a non-glass container, which can react with vinegar.
- Overcooking the vinegar mixture, which can diminish flavor.
