Ingredients

  • 2 medium red onions thinly sliced, I like to use a mandoline for slicing

Instructions

  • Pack the sliced onions into a large quart jar.

  • In a saucepan over low heat, whisk together the vinegar, water, maple syrup, miso, and salt until smooth. You just want to warm it enough that the miso dissolves. Do not simmer or boil.

  • Pour the brine over the onions, making sure they’re fully submerged. Press down gently.
