Ingredients

Instructions

  1. Step 1: In a medium bowl, whisk together 3 tbsp white miso paste, 1/4 cup rice vinegar, 1 cup water, 1 tsp sea salt, 1 tbsp grated ginger, and 1/4 tsp red pepper flakes until smooth.
  2. Step 2: Place 1 lb julienned carrots in a sterilized quart-sized mason jar, then pour miso brine over them until fully submerged, pressing down to remove air pockets.
  3. Step 3: Seal jar with an airtight lid and let sit at room temperature for 48 hours, burping the lid daily to release gas (after 24 hours, check for faint fizzing).
  4. Step 4: After fermentation, refrigerate for 7-10 days to develop deeper flavor, then drain before serving. The carrots should have a bright orange hue and tangy-sweet umami flavor with a slight crunch.
