How to slice onions for pickling
- First, remove any loose, dry onion skin and place the onion on a cutting board with the root end to one side.
- Then, using a sharp knife carefully slice off the root end and the tip of the onion.
- Slice the skin of the onion and peel off the outer layer.
- Carefully turn the onion so that cut off edge of the onion is closest to the knife and slice off thin slices.
- Continue to slice the onion until the entire onion is thinly sliced and ready to be pickled.
How to make pickled red onions:
- Slice the onions: peel and thinly slice red onions into circles or half-moons, depending on your preference.
- Dissolve the sugar and salt: Bring the water, vinegar, sugar and salt to a simmer to dissolve the sugar and salt.
- Blanch the onions: Place the sliced onions in a strainer and place the strainer over a bowl or in the sink. Pour boiling water over the onions, quickly blanching them, removing some of the bite of the onions and let them drain.
- Add the onions to the jar: Add the onions and any additional flavorings such as peppercorn or garlic to the jar and pour the warm brine mixture over the onions.
- Store: The onions will be ready in about 30 minutes or when they have cooled, but are better after a few hours. Store in the refrigerator. They will keep for several weeks, but are best in the first week.
📝 FREQUENTLY ASKED QUESTIONS, ANSWERS AND TIPS:
Pickled red onions need to be refrigerated and consumed within 2 weeks. The only time pickled vegetables should be stored on the shelf is if they have been properly canned.
I am using white vinegar with 5% acidity for this recipe but apple cider vinegar, white wine vinegar or champagne vinegar could be used.
Pickled red onions are a delightful combination of bite and sweet. The more sugar you add the sweeter they are. I love that pickled onions still have a crunch to them that is the perfect addition to grilled burgers, flank steak fajitas, any taco, or as part of a charcuterie and cheese board.
