Step‑by‑Step Instructions for Quick Pickled White Onions Recipe
Step 1: Prep Onion
Start by peeling the medium white onion, then slice it as thinly as possible, about 1/8-inch thick. Don’t rush this step, as the thinner the slices, the quicker they will pickle! Aim for uniformity to ensure even pickling. You should end up with a beautifully arranged pile of crisp onion rings ready for brining.
Step 2: Make Brine
In a small saucepan, combine 1 cup of unseasoned rice vinegar, 1 tablespoon of sugar, and 1 tablespoon of kosher salt. Place it over medium-high heat and stir frequently until the sugar and salt are completely dissolved, and the mixture begins to boil—this should take about 3 to 5 minutes. Once bubbling, remove it from the heat, letting the fragrant steam fill your kitchen!
Step 3: Combine
Transfer your sliced onions into a clean glass jar or a bowl. Carefully pour the hot brine over the onions, ensuring they are completely submerged. You might need to press down gently on the onions with a spoon or a clean weight to keep them below the brine. The vibrant color of the onions will brighten as they soak up the zesty pickling liquid.
Step 4: Cool
Allow the jar of onions to sit uncovered at room temperature for about 30 minutes. During this cooling period, the onions will absorb the vinegary brine, transforming into a tangy delight. Keep an eye on the jar as the onions change color, becoming a beautiful, translucent shade of pink.
Step 5: Seal and Refrigerate
After they’ve cooled, seal the jar tightly with a lid and place it in the refrigerator. Your quick pickled white onions can be enjoyed after just 30 minutes, but their flavor will deepen and improve if allowed to chill overnight. They are now ready to elevate your dishes with their delightful crunch and tangy flavor!
