Pickled Red Onions Recipe
Pickled Onions add a sweet and tangy zing to tacos, Salmon Bowls, sandwiches, and salads. Pickling onions is easier than you think. The brine only takes minutes to prepare, and no water bath is needed. Pack a pint jar with sliced onions, pour the hot brine over the onions, let them cool, and then place them in the refrigerator. That’s it!
You typically see pickled red onions. I have never tried a different type of onion and am not sure what it would taste like, but any onion will work. Pickling onions takes the edge off the flavor, making them not as strong. This is a plus for people who might not otherwise put onions on a dish.
