Let’s get pickling!

Ingredients:

The Process: Preparing Your Onions

The first step in our pickling adventure is preparing the star of the show: the red onions. You want to aim for a uniform slice so that each piece pickles evenly. The best way to achieve this is to peel the onions, trim off the stem end (the part with the roots), but leave the root end intact. This helps hold the onion together as you slice it, preventing it from falling apart into disorganized pieces. Then, slice the onions thinly. A mandoline slicer is ideal for this, as it will give you perfectly even, paper-thin rings. If you don’t have a mandoline, a sharp knife will work perfectly, just take your time and try to keep the slices as consistent as possible. The thinner the slices, the quicker they will pickle and the more tender they will be. Once sliced, you can separate the rings with your fingers.

Crafting the Brine: The Heart of the Pickles

Now, let’s talk about the magic liquid that will transform our raw onions into delightful pickles: the brine. This is where all the flavor comes from. In a medium saucepan, we’re going to combine our liquids and seasonings. Pour in the 1 1/4 cups of water and the 1 1/4 cups of white vinegar. White vinegar is a classic choice for pickling because its clean, sharp flavor doesn’t compete with the other ingredients and it provides the necessary acidity for preservation. Next, we’ll add the sugar. I’ve noted “sugar (of choice)” because you can experiment here! Granulated white sugar is perfectly fine, but you could also use cane sugar for a slightly richer flavor, or even a bit of maple syrup if you want a hint of its distinctive sweetness. For this recipe, 3 tablespoons will provide a pleasant balance to the acidity of the vinegar. Then comes the salt. We’re using 1 tablespoon of sea salt. Sea salt has a cleaner flavor profile than iodized table salt and dissolves beautifully. Finally, if you enjoy a little warmth, you can add the red pepper flakes now. A quarter to a half a teaspoon is usually enough to provide a gentle kick without making the pickles overtly spicy. This addition is entirely optional, but I find it adds a lovely subtle depth.

Heating and Dissolving: Bringin extractg it all Together

With all the brine ingredients in the saucepan, it’s time to bring them together. Place the saucepan over medium heat on your stovetop. Stir the mixture occasionally as it heats up. Our goal here is not to boil the brine vigorously, but rather to heat it just enough to ensure that the sugar and salt dissolve completely. You’ll know it’s ready when you can no longer see any granules of sugar or salt at the bottom of the pan. Stirring will help speed up this process. Once everything is dissolved, remove the saucepan from the heat. Let the brine sit for a few minutes to cool down slightly. While it’s not essential for it to be completely cool, you don’t want to pour boiling hot liquid directly over your onions, as this can sometimes make them overly soft or even cook them slightly, which isn’t the desired texture for pickled onions.

Assembling Your Pickled Onions: The Final Touch

Now for the exciting part – combining the onions and the brine! Get a clean, airtight jar or container. I prefer glass jars, as they don’t absorb odors and are easy to see the beautiful color of the pickled onions. Carefully place your sliced red onion rings into the jar. Try to pack them in fairly snugly, but don’t worry if they seem a little loose. Once your onions are in the jar, it’s time to pour the warm brine over them. Carefully pour the brine into the jar, making sure that all the onion slices are submerged. If by chance you don’t have quite enough brine to cover them completely, you can quickly whip up a little more following the same proportions. Gently shake the jar or press down on the onions with a spoon to ensure they are all submerged.

The Waiting Game: Patience is a Virtue

This is perhaps the most crucial step: waiting! While you’ll see a subtle change in color pretty quickly as the onions begin extract to absorb the brine, the best flavor develops over time. Once the jar has cooled to room temperature (this usually takes about an hour or so), seal the lid tightly and transfer the jar to the refrigerator. For the most vibrant flavor and best texture, I recommend letting them pickle for at least a few hours, but ideally overnight. The longer they sit, the more the flavors will meld and the more tender the onions will become. You’ll notice the onions will deepen in color, becoming a more intense ruby-red. After about 24 hours, they’ll be ready to enjoy.

Storage and Enjoyment: A Kitchen Essential

Once your pickled red onions are ready, they will keep in the refrigerator for several weeks, typically up to 3-4 weeks. They will continue to soften slightly as they sit, so the texture will change a bit over time. Don’t be surprised if you find yourself reaching for them more often than you initially thought! They are fantastic on avocado toast, as a topping for burgers and hot dogs, mixed into potato salad or coleslaw, scattered over a grain bowl, or as a vibrant accompaniment to any Mexican-inspired dish. They add a bright, refreshing contrast to rich or savory flavors. So, go ahead, make a batch, and get ready to add a delightful pop of flavor and color to all your meals!

Frequently Asked Questions:

How long do pickled red onions last?

When stored properly in an airtight container in the refrigerator, these pickled red onions can last for up to 2-3 weeks. The acidity of the brine acts as a natural preservative, but their crispness will diminish over time.

Can I adjust the sweetness of the brine?

Absolutely! The sweetness is easily adjustable to your preference. If you prefer them less sweet, start with a tablespoon of sugar and taste the brine before pouring it over the onions. You can always add a little more to achieve your desired sweetness level.

What if I don’t have red grape juice vinegar?

While red grape juice vinegar provides a lovely color and depth, you can substitute it with other vinegars like apple cider vinegar or white grape juice vinegar. The color might be slightly different, but the tangy flavor will still be delicious.
