  • 1 cup raw cashews
  • ½ cup filtered water
  • 1 tablespoon freshly squeezed lemon juice, plus more to taste if desired
  • 1 tablespoon distilled vinegar
  • 1 teaspoon Dijon mustard
  • ½-1 teaspoon fine sea salt, plus more to taste if desired


  • Soak cashews in boiling water for 30 minutes or in cold water at room temperature (covered) for 6-8 hours.
  • Add filtered water and the remaining ingredients to a high-powered blender.
  • Drain and rinse cashews and add to the blender.
  • Blend on high for about a total of 5-7 minutes until very smooth and creamy. You will need to stop and scrape the sides of the blender with a silicone spatula a few times during the process. Taste test and add more lemon juice and/or salt if desired and blend again. Use right away or refrigerate until ready to use.


Store mayo in an airtight glass container in the refrigerator (a mason jar works best) for up to a week.
