Mexican Picked Red Onions

Keri Bevan
These authentic Mexican pickled red onions get their zesty flavor from generous lashings of lime juice. If you've ever had Mexican street tacos, you'll be familiar with these tangy pink onions. While Mexican onions are the natural sidekick to tacos, you can also use them to brighten up salads, burgers and salsas with this easy quick pickle recipe.

Ingredients
 
 

  • 2 small red onions
  • 4 limes juice of
  • ½ cup boiling water
  • 3 tablespoons apple cider vinegar * or rice vinegar or white wine vinegar
  • 1 teaspoon sea salt

Instructions
 

  • Thinly slice the onion into half moon shapes.
  • Squeeze the juice out of the limes into a small bowl and set aside.
  • Boil the water and transfer it to a non-reactive bowl large enough to hold your onions. Stir in the vinegar, lime juice and salt.
  • Add the onions to the brine and press down with the back of the spoon to ensure they're all covered in the brine. Allow the onions to soak for at least 30 minutes to overnight. The longer the onions soak in the brine, the softer they'll get and the pinker the brine will turn.
  • Transfer to a glass jar, and store in the fridge.

Notes

*Note that Mexican pickled onions are always tangy with a sour note. If the taste is too sour for your liking, add a teaspoon or two of sugar or agave nectar.
