Instructions:
The process of making pickled red onions is remarkably straightforward, a testament to how simple ingredients can yield such impressive results. We’ll start by preparing the star of our show, the red onion, and then move on to creating the brine that will work its magic.
Step 1: Preparing the Onion
The first step is to prepare your red onion. You’ll want to peel the outer papery skin off the onion. Then, trim off the top and root end. For pickling, the thickness of your onion slices is key. Aim for thin, uniform slices. A mandoline slicer is your best friend here, as it will ensure consistency, which is important for even pickling. If you don’t have a mandoline, a sharp knife and a steady hand will do the trick. Slice the onion in half from root to tip, then slice each half thinly. The thinner the slices, the quicker they will pickle and the more readily they will absorb the brine. Avoid slicing too thick, as they might remain a bit too crisp for some preferences.
Step 2: Making the Brine
While your onion is sliced, it’s time to prepare the pickling liquid, often called a brine. In a small saucepan, combine the white vinegar, water, sugar (if using), and kosher salt. Place the saucepan over medium heat. Stir the mixture gently until the sugar and salt have completely dissolved. You don’t need to bring this mixture to a rolling boil; just heat it enough to ensure everything is dissolved. Once dissolved, remove the saucepan from the heat. This brine is the flavor base for your pickled onions, and the balance of vinegar, water, sweetness, and salt is what creates that characteristic tangy and slightly sweet profile.
Step 3: Combining Onion and Brine
Now for the satisfying part: combining the prepared onion with the warm brine. You’ll need a clean, heat-safe jar or container. A glass jar with a tight-fitting lid is ideal. Carefully place the thinly sliced red onion into your chosen jar. Once the onion is nestled in, pour the warm brine over the top. Make sure the onion slices are completely submerged in the brine. If you find they’re floating a bit too much, you can gently press them down with a spoon to ensure they are all covered. The heat from the brine will also help to slightly soften the onions, making them more tender.
Step 4: The Waiting Game (and the Transformation!)
This is where patience comes into play, but the transformation is worth it. Let the jar sit at room temperature for at least 30 minutes. During this time, you’ll witness a beautiful color change. The onions will start to turn a vibrant pink as they soak up the brine and release their natural pigments. For a more pronounced pickle and deeper flavor, you can let them sit for up to an hour or even two at room temperature. The longer they sit, the more infused they become.
Step 5: Refrigerate and Enjoy
After the initial resting period at room temperature, it’s time to move your pickled red onions to the refrigerator. Seal the jar tightly and place it inside your fridge. They will continue to develop their flavor and texture as they chill. Ideally, let them chill for at least a couple of hours before diggin extractg in, though they are often delicious even after an hour. The longer they sit in the refrigerator, the better they become. They can be stored in the refrigerator for up to 2-3 weeks. The flavor will continue to deepen and evolve over time.
These pickled red onions are incredibly versatile. Add them to avocado toast for a zesty kick, toss them into a fresh salad for added crunch and tang, or pile them onto your favorite burger or tacos.
