Quick Pickled Red Onions
This is not a long-term canning process; it is a kitchen staple meant to be made and consumed within a fortnight. The heat of the brine softens the raw bite of the onion while turning them a vibrant, translucent pink.
Consistency is your primary goal.
Slice the onions as thin as your knife skills allow so they absorb the brine evenly and maintain a crisp texture rather than turning soggy.
- Mandoline or sharp chef's knife
- Small saucepan
- Wide-mouth glass jar with a tight-fitting lid
What goes in.
- 1 largered onion, sliced into paper-thin half-moons
- 1/2 cupapple cider vinegar
- 1/2 cupwater
- 1 tbspkosher salt
- 1 tbspgranulated sugar
Bring the brine to a simmer
Dissolving the salt and sugar in simmering liquid ensures the onions remain evenly seasoned from top to bottom.
The method.
Prep the onions
Pack the sliced onions into a clean glass jar. Press them down firmly, but do not crush them.
Prepare the brine
In a small saucepan, combine vinegar, water, salt, and sugar. Place over medium heat until the sugar and salt have fully dissolved and the liquid is steaming.
Submerge
Pour the hot brine directly over the onions. Ensure all onion edges are submerged; if they aren't, use a clean spoon to push them down.
Cool and store
Leave the jar open on the counter until it reaches room temperature. Screw on the lid and move to the refrigerator.
Other turns to take.
Spiced
Add a teaspoon of whole black peppercorns, a crushed clove of garlic, or a dried chili pepper to the jar before pouring the brine.
Herb-infused
Tuck a sprig of fresh oregano or thyme into the jar for an earthy undertone.
When it doesn't go to plan.
If the onions take on a neon pink hue after an hour, that is normal; the acidity reacts with the natural pigments in the onion.
Use a mandoline if you have one to ensure every slice is uniform, which keeps the texture consistent.
Do not discard the brine once the onions are gone; it adds a sharp acidity to salad dressings or pan sauces.
The ones that keep coming up.
Why use red onions instead of white or yellow?
Red onions provide a distinct color and a slightly milder flavor profile that holds up well to acidity without becoming overly pungent.
Can I use plain white vinegar?
Yes, but white vinegar is harsher and more aggressive than apple cider or red wine vinegar. If using white, consider doubling the sugar to balance the bite.
