Instructions:
Prepare the Onion
The first step is to prepare your red onion. You’ll want to start with a large one to get a good amount of pickled goodness. Begin extract by peeling off the papery outer skin of the red onion. Once peeled, trim off both ends. Then, slice the onion very thinly. A mandoline slicer is your best friend here for achieving uniform, thin slices, which ensures they pickle evenly. If you don’t have a mandoline, a sharp knife will work, but take your time to get them as thin as possible. The thinner the slices, the quicker they will pickle and the more tender they will become. You want slices that are almost translucent. After slicing, place all the onion slices into a heatproof jar or a bowl. I prefer using a glass jar because it’s easy to store the pickled onions in it once they are ready. A pint-sized or quart-sized jar usually works well for one large onion.
Make the Brine
Now, let’s get to the brine, which is where all the magic happens. In a small saucepan, combine the white vinegar, water, sugar, and kosher salt. White vinegar provides the sharp tang necessary for pickling. The water helps to dilute the vinegar slightly, making the brine less harsh. The sugar, as noted in the ingredients, is optional. If you prefer a purely savory and tangy bite, you can omit it entirely. If you choose to use it, it balances the acidity and adds a subtle sweetness that is quite appealing. If you’re watching your sugar intake or prefer a less sweet pickle, a sugar substitute like stevia or erythritol can be used in a comparable amount, or you can reduce the quantity to ½ tablespoon. Use kosher salt because its larger flakes dissolve nicely and provide a clean salt flavor. Stir these ingredients together in the saucepan until the sugar and salt are completely dissolved. It’s important that they dissolve thoroughly before heating.
Heat the Brine
Once your brine ingredients are combined and stirred, it’s time to heat them. Place the saucepan over medium heat on your stovetop. Bring the mixture to a gentle simmer. You don’t need a rolling boil; just a simmer is sufficient. The purpose of heating the brine is to help the salt and sugar dissolve completely and also to slightly warm the onions, which aids in the pickling process and helps them absorb the flavors more readily. Stir occasionally as it heats up to ensure everything is well incorporated. Once it reaches a simmer and you can see that the salt and sugar crystals have vanished, remove the saucepan from the heat. Be careful not to overheat it, as you don’t want the vinegar to evaporate too much, which would concentrate its potency more than desired.
Combine and Steep
Carefully pour the hot brine over the thinly sliced red onions in your heatproof jar or bowl. Make sure that all the onion slices are fully submerged in the brine. If any slices are peeking out, you can gently press them down with a spoon. The hot liquid will immediately begin extract to work its magic, and you’ll notice the onions starting to soften and their color begin extractning to change, turning a lovely shade of pink. This transformation is quite satisfying to watch! Allow the onions to steep in the hot brine for at least 30 minutes at room temperature. During this time, they will start to soften and absorb the tangy, slightly sweet flavors of the brine. The longer they steep at this stage, the more pronounced the pickling will be, so feel free to let them sit for an hour if you have the time.
Chill and Store
After the initial 30-minute (or longer) steeping period at room temperature, it’s time to transfer your pickled red onions to the refrigerator. If you used a bowl for steeping, carefully transfer the onions and brine into an airtight container or a clean glass jar. Seal the container tightly. Place the jar in the refrigerator. The cold temperature will further the pickling process and help the onions develop their full flavor and texture. Ideally, you’ll want to let them chill for at least an hour before serving, but they truly shine after a few hours or even overnight. The longer they sit in the refrigerator, the more tender and flavorful they will become. They can be stored in the refrigerator for up to 2-3 weeks, making them a fantastic make-ahead condiment. When you’re ready to use them, simply drain off any excess brine (or leave some on if you like them extra tangy) and add them to your favorite dishes. Enjoy the bright, zesty addition they bring!
