Red Onions: I love the pink color of the pickled onions. If you don’t have red onions, use yellow or white onions. I’ve even used sweet onions.
Vinegar: I use white and apple cider vinegar in this recipe. I’ve also used wine, malt, and rice vinegar for pickling.
Sweetener: This recipe uses granulated sugar. Other sweeteners I use are honey, maple syrup, and monk fruit.
Water: either bottled or tap
Pickling Salt: Table salt has an anticaking additive that will cloudy the pickling solution.
Celery Seed: optional; I love the heady flavor it adds to the pickled onions.
