Instructions:
Prepare the Onion: Begin extract by peeling your large red onion. The key to beautiful pickled onions is how you slice them. You want to aim for thin, uniform slices. I find that using a mandoline slicer is the easiest way to achieve this, but a sharp knife and a steady hand will work just as well. Slice the onion into rounds, about 1/8-inch thick. Don’t worry if some pieces are slightly thicker or thinner; it won’t drastically affect the outcome. However, the more uniform your slices, the more evenly they will pickle. Once sliced, place all the onion rings into a heatproof bowl or jar. If you’re using a jar, a wide-mouth mason jar is ideal for easy filling and access. Ensure your bowl or jar is large enough to comfortably hold the onions and the pickling liquid.
Create the Brine: In a small saucepan, combine the white vinegar, water, sugar, and kosher salt. Place the saucepan over medium heat. Stir the mixture occasionally, just enough to help the sugar and salt dissolve. You do not need to bring this mixture to a rolling boil. Simply heat it until the sugar and salt are completely dissolved. This will take a few minutes. Once dissolved, remove the saucepan from the heat. This quick heating process helps to meld the flavors and ensures the salt and sugar are fully incorporated, creating a perfectly balanced brine. The vinegar provides the essential acidity, the water dilutes it to a pleasant tang, and the sugar and salt temper the sharpness while adding depth of flavor. Remember, you can adjust the sugar level here based on your preference – a little less for a more assertive pickle, or a touch more if you prefer it on the sweeter side.
Combine and Pickle: Carefully pour the warm brine over the sliced red onions in your bowl or jar. Make sure all the onion slices are submerged in the liquid. If necessary, gently press down on the onions with a spoon to ensure they are fully immersed. This is crucial for even pickling. The warm brine will immediately begin extract to work its magic, softening the onions slightly and infusing them with that signature bright pink hue. As the onions sit in the brine, you’ll notice the color change; this is a visual indicator that the pickling process is underway. Once everything is submerged, cover the bowl or jar tightly. If you are using a bowl, you can cover it with plastic wrap or a lid. If you are using a jar, screw on the lid securely.
Chill and Marinate: Now comes the waiting game, but it’s a delicious one! Let the mixture sit at room temperature for about 30 minutes to an hour. This initial period allows the onions to begin extract softening and absorbing the flavors of the brine. After this initial resting period, transfer the covered bowl or jar to the refrigerator. This is where the magic truly happens. The cold temperature slows down the enzymatic processes, allowing the onions to develop their complex pickled flavor without becoming overly mushy. For the best results, let them chill for at least 2 hours, but I highly recommend letting them pickle for a minimum of 4-6 hours, or even better, overnight. The longer they marinate, the more intense and satisfying the flavor will become. You’ll see the onions transform from a crisp raw onion to a tender, vibrant, and deeply flavorful pickled delight.
Serving and Storage: Once your pickled red onions have reached your desired level of pickling (usually a few hours to overnight in the fridge), they are ready to be enjoyed! You can drain them before serving if you prefer a less vinegary bite, or serve them with a little of the brine for extra flavor. These pickled red onions are incredibly versatile. They are fantastic piled high on avocado toast, layered into gourmet burgers, sprinkled over salads for a pop of color and tang, or as a zesty accompaniment to grilled fish or chicken. They add an instant upgrade to so many dishes. Store any leftovers in an airtight container or the origin extractal jar in the refrigerator. They will keep well for at least 2-3 weeks, though I doubt they’ll last that long once you taste them! The flavor often continues to deepen and improve over time. Enjoy experimenting with all the ways you can incorporate these vibrant gems into your cooking!
