Three Mason Jars full of Pickled Red Onions

Do I need to use a red onion? Can I use white or yellow?

Red onions are best suited for pickling because they have a more mild flavor. While you can certainly pickle white or yellow onions, they both have much sharper, more potent onion flavors. Yellow onions in particular are rarely consumed raw. Red onions will produce the best results.

When pickling any kind of vegetable, you should use containers that are suitable for fermentation and pickling. These include stoneware, glass, and food grade plastic containers. Mason jars are the most commonly used containers for pickling for home cooks.
