Quick Pickled Red Onions

1 medium red onion ½ cup hot water (it does not need to be boiling hot) ½ cup apple cider vinegar 1 tablespoon honey or maple syrup 1 ½ teaspoons kosher salt Optional flavor boosters (see below) Thinly slice the onion with a knife or mandoline, then place in a 16-ounce jar. Add any optional flavor boosters. In a measuring cup, stir together the water, vinegar, honey, and salt. Carefully pour the brine into the jar over the onions. Cover with a lid and refrigerate. They'll be ready to eat after about an hour in the fridge (they'll be vibrant pink), and will keep for 2 to 3 weeks in the fridge. Give Your Pickled Onions A Flavor Boost! These pickled red onions taste amazing as is. But if you want to switch things up a bit – here are a few ways to add some fun flavors and give them a little boost. Stir in whole spices. From black peppercorns and coriander seeds to star anise and fennel seeds, whole spices are a great way to subtly add your favorite seasonings. Add a punch of garlic. Stir sliced garlic pieces into the mix – this is my absolute favorite! Heat it up. Add a dash of cayenne or red pepper flakes for a hint of spice. Add your favorite herbs. I love to add sprigs of dill, or fresh basil and mint leaves. But you can honestly add whichever herbs you like, depending on how you want it to taste.
