Recipe: Lacto-fermented Fruit Leather

Cultured fruit leather is a great way to get beneficial bacteria into your kid's diet and makes a great snack to pack in lunches.


  • 2 to 3 pounds of fruit (apples, bananas, pears, berries, mango, kiwi, etc.)
  • Spices to taste (cinnamon, nutmeg, etc.)
  • Sweetener to taste
  • 2 Tbsp. whey or water kefir


  1. Prepare the fruit (core apples, remove unwanted seeds from other fruits, etc.) and cut up the fruit into manageable pieces.
  2. Process the fruit in a blender, food processor or food mill until the mixture is relatively smooth.
  3. Mix in the spices, sweetener, and whey or water kefir.
  4. Transfer to a quart jar, leaving at least an inch of headspace.
  5. Cover the jar with a tight lid, airlock lid, or coffee filter secured with a rubber band.
  6. Culture at room temperature (60-70°F is preferred) until desired flavor and texture are achieved, about 1-3 days. If using a tight lid, burp daily to release excess pressure.


  1. Spread the cultured fruit mixture on sheets of unbleached parchment paper or a silicon sheet that fits inside your food dehydrator, or on a baking sheet if using your oven. Tip: If the mixture is very watery, try straining the mixture through a tea towel or tight-weave cheesecloth to thicken it up a bit. The strained juice is delicious to drink and contains beneficial bacteria from the culturing process.
  2. Allow the fruit leather to dry overnight or for 8 to 24 hours. The exact length of time will depend on the temperature used and the thickness of the mixture. We recommend setting your oven or food dehydrator to 110°F or less to preserve the beneficial bacteria.
  3. The fruit leather is done when it is smooth and no longer sticky.

Store the finished fruit leather in an airtight container.
