Equipment

  • 1 quart jar with lid
  • fermentation weight or small, clean stone

Ingredients

  • 1 lb beets about 2-3 medium beets, peeled and sliced or cubed into ¼-inch pieces
  • 2 teaspoons salt non-iodized, fine
  • 2 cups water non-treated

Optional Add-Ins

  • 2 cloves Garlic lightly smashed
  • 1 sprig Fresh dill or ½tsp dried dill seed
  • 1 Bay leaf
  • ½ teaspoon Peppercorns
  • ½ teaspoon Mustard seeds
  • ½ teaspoon Fresh ginger thinly sliced or grated
  • ¼ teaspoon Red pepper flakes optional heat

Instructions

  • Prep beets: Wash, peel (optional), and cut into slices, sticks, or ¼-inch cubes.
  • Pack jar: Add beets and any optional add-ins to a clean quart jar, leaving 1–2 inches of headspace.
  • Make brine: Dissolve 2 teaspoons salt in 2 cups water (2% brine).
  • Pour & submerge: Cover beets completely with brine. Add a weight to keep everything submerged.
  • Ferment: Cover loosely and ferment at room temperature for 7–14 days, burping daily if needed.
  • Store: When tangy to your liking, refrigerate with beets fully submerged.

Notes

  • Salt Ratio: Use a 2% brine (20 g salt per 1 liter water). For this recipe, that equals 2 tsp salt per 2 cups water.
  • Submersion Matters: Keep beets fully submerged under brine at all times to prevent mold.
  • Fermentation Time: Ferment at room temperature (65–75°F) for 7–14 days. Start tasting after 1 week.
  • What’s Normal: Bubbles, cloudy brine, and a tangy aroma are signs of healthy fermentation; mold is not.
  • Storage: Once fermented to your liking, refrigerate with beets submerged in brine. Keeps for several months.
  • Flavor Add-Ins: Garlic, dill, bay leaf, peppercorns, mustard seed, or ginger may be added before fermenting.
