Instructions
Par-blanch
Bring 2 cups of water to a boil in a small saucepan. Place sliced red onion in a fine mesh strainer. Slowly pour hot water evenly over all of the onions.
Prepare the vinegar solution
In the same saucepan, stir together vinegar, water, salt and sweetener. Cook over medium-high heat until the mixture reaches a simmer and sweetener and salt have dissolved.
Marinate
Place the thinly-sliced onions (and any additional flavoring ingredients) in a mason jar. Pour the hot vinegar mixture over the onions. Put on the lid and gently shake the jar around to make sure everything is coated and mingling together..
Let the onions marinate for at least 30 minutes and up to a day (for maximum flavor).
Serve immediately after 30 minutes or refrigerate the onions in a sealed container for up to a month.
Notes
If you want a stronger onion flavor, skip the par-blanching step.
If you’re looking for more crunch, slice the onions a bit thicker.
For a sweeter pickled red onion, double the amount of sweetener used in the vinegar solution.
Onions will soften the longer they are allowed to sit in the vinegar solution.
