Making Pickled Red Onions is so incredibly easy and quick! About 5 minutes and a handful of ingredients that you most likely have at home is all takes! And they go so good with just about everything, they will become your favorite condiment for sure.
Place the sliced onions, garlic clove and peppercorns in a 0.75l glass canning jar (or any other similar container, preferably one that can be used for storage)
In a large glass measuring cup, combine the hot water, vinegar, maple syrup and salt and stir to help dilute the salt. Pour this pickling mixture over the sliced onions, cover loosely and let them set for about an hour.
After that time, your pickled onions are ready to use, but they do taste better and get crunchier once they've had a chance to fully chill.
Close the lid tightly and transfer your onions to the fridge, where they will keep for about a month.
*The flavor of pink peppercorns complements superbly well that of the pickled onions, but if you can't find them or don't have any on hand, feel free to use a few black peppercorns instead, or omit them altogether.
