Prep time



Spice up taco Tuesday with these divine quick pickled onions. This recipe calls for measuring in grams, which requires a kitchen scale. Don't have one? This is the Escali Digital Food Scale that I use now. I love it!


  • 200 grams chopped red onion

  • 200 grams sauerkraut brine

  • 100 grams raw apple cider vinegar

  • 5 grams sea salt

  • Juice of one lime

  • Mustard seeds or peppercorns (optional)


  • Wash and sanitize fermentation equipment (a splash of cheap vodka will do the trick).
  • Set your scale on a flat surface and set it to weigh in grams.
  • Place a clean mason jar on the scale, and tare/zero the scale.
  • Add 200 grams of Sauerkraut Brine to the mason jar.
  • Add 100 grams of apple cider vinegar to the mason jar.

  • When cold, you're ready to enjoy!
