Why This Recipe Works
Such an easy recipe for a big payoff in flavor! They add a pop of color and a tart, crunchy flavor that can really elevate a dish. Plus, they're super easy to make! Just thinly slice some red onions, and then soak them in a mixture of vinegar, water, sugar, and salt for at least an hour. These onions just pickle me pink!
Table of Contents
- Onions: You can use a red, brown, yellow, or white onion.
- Brine liquid: Vinegar( apple cider or white distilled), water, salt, and sugar. Vinegar must have 5% acidity. This combination of ingredients will be a slightly sweet brine. For a sweeter brine use more sugar for a tangy brine use less sugar.
- Seasoning: I found just a little garlic and peppercorns give me just the right amount of seasoning.

Recipe Notes and Tips
- The longer you leave the onions in the brine the more"pickled" they become. This is why I prefer making in small batches.
- It'simportantt o have the onions completely submerged in the brine liquid, if needed push the onions down with a small spatula.
- For really thin slices of onion, use a mandolin slicer.
- For a sweeter brine use more sugar for a more tangy brine use less sugar.
