Prepared Horseradish

How to use prepared horseradish.

5 from 1 review

Homemade prepared horseradish is so easy to make. This traditional recipe is fermented and will last for months in the fridge. See the section above for six ways to serve preserved horseradish.


Units Scale
  • 2 cups of horseradish, peeled and chopped (about 10 oz)
  • 1 cup raw apple cider vinegar (with mother)
  • 1/2 tsp salt (non-iodized)


  1. Horseradish is quite strong, so I recommend making this recipe outside. At least for the peeling and mixing. Otherwise, you may end up in tears!
  2. Start by peeling the horseradish. Depending on how fresh it is, you may be able to use a peeler, but tough and gnarly horseradish root can be peeled with a knife. Rinse the root after peeling.
  3. Coarsely chop the root, then place the chunks in a food processor or blender. Grind until the horseradish is finely diced.
  4. Measure two cups of loosely packed horseradish root into a bowl. Stir in the salt.
  5. Pack the salted horseradish into a small jar. Pour over the cider vinegar. You need just enough to fully submerge the horseradish (3/4 cup to 1 cup).
  6. Place the jar in a dark cupboard and leave it to ferment for at least 5 days and up to 4 weeks.
  7. After fermenting, cap with an air-tight lid and store in the refrigerator. Use within 6 months


  • Store-bought horseradish is high in added sulfites, which is why it stays white. Your horseradish will turn slightly brown over time. It should last for up to 6 months in the fridge as long as you don’t double-dip.
  • I find it handy to ferment in the final serving jar. This recipe will fit in one 500mL mason jar or two 1 cup mason jars.
  • To ferment the horseradish, it is important to use raw cider vinegar with a mother. If you can’t find raw ACV, then simply skip the fermentation step and place the horseradish directly in the fridge. It will end up being vinegar pickled rather than fermented.
