Fermented Peanut Butter recipe

Fermented Peanut Butter is a great homemade recipe that allows you to eat peanut butter without aflatoxins. Fermenting also reduces oxalates, adds probiotics and makes the nutrients in peanut butter more bioavailable.

Ingredients

  • 2 cups peanuts roasted* (for best nutrition: sprouted and Valencia variety, de-hulled) *See how to roast peanuts in the Notes section below.
  • 3/4 cup water
  • 1/2 teaspoon sea salt optional
  • 2 to 3 capsules probiotic , depending on size and strength, or Vegan yogurt starter

Instructions

  • Blend roasted (and de-hulled, if needed) peanuts and optional sea salt in food processor until peanuts become peanut butter.
  • With motor running, gradually add water through the feed tube. Blend until water is fully incorporated and peanut butter is creamy. Take off the lid. Use a spatula to scrape the sides and bottom so they get mixed in with the next step.

  • Sprinkle in probiotic, and blend just briefly to mix.
  • Transfer peanut butter to fermentation vessel or glass jar. Cover loosely. Place in steadily warm location for about 15 hours. (If you have an Instant Pot with a Yogurt setting, you can ferment directly in the insert pot, if you like.) Note: Your peanut butter may have a darker "skin" over the surface after fermenting, which is fine; it's just darker and firmer where it was exposed to the air. This can be stirred in or ignored.

  • Transfer to fridge, or eat immediately. Store Fermented Peanut Butter in the fridge for 1 month, or possibly much longer.

Notes

Learn how to soak and "sprout" your peanuts here.

Sprouting raw peanuts simply means to activate them, creating a more digestible peanut. You will not actually see a sprout.

How to roast peanuts

  1. Preheat the oven to 350 degrees F.
  2. Spread peanuts in a single layer on a large rimmed baking sheet.
  3. Roast about 10 minutes, until golden brown and glossy with fat.
  4. Allow to cool fully before processing into peanut butter.
