MAKES: ABOUT 1 QUART
INGREDIENTS:
- 2 pounds apples, cored and cut into large chunks
- 2½ pounds beets, peeled and cut into large chunks
- 1 pound horseradish, peeled and cut into large chunks
- 2 tablespoons finely ground unrefined sea salt, plus more as needed
INSTRUCTIONS:
- Shred the apples, beets, and horseradish in a food processor fitted with the shredding disk in batches.
- Transfer the shreds to a large mixing bowl, stir in the salt, and knead for about 3 minutes to break up the fruit and roots.
- Cup by cup, transfer the mixture to a quart-size crock and pound it down with a wooden dowel or spoon until it releases its juice.
- Continue packing the crock until the roots and apple mixture are exhausted and the brine created by the juice and salt completely submerges the relish.
- Seal the crock and place it in a warm spot in your kitchen where it will ferment.
- Check the crock periodically to ensure that the relish remains submerged in brine. If it does not remain submerged, whisk 1 teaspoon of unrefined sea salt into 1 cup of water and pour this over your relish.
- After about 10 days, taste the relish. If you prefer a sourer flavor, let it ferment 5 to 7 days further.
- Transfer the relish to the refrigerator or other cold storage when it has reached a flavor to your liking.
- The relish should keep for 6 months or longer.
