Equipment

  • Bowl for soaking cashews
  • Blender high-speed preferred, but standard works
  • Small saucepan optional, for warming

  • 1 tbsp nutritional yeast

  • ½ tsp fine sea salt
  • 1 tsp olive oil optional, adds richness

    Option B (Quick): Pour boiling water over cashews and soak for 20–30 minutes.
    Option C (Fastest): Simmer cashews in a small pot of water for 10 minutes.Drain and rinse before using.
  • Blend the Sauce
    Place soaked cashews in a blender.
    Add water (or plant milk), lemon juice, garlic, nutritional yeast, onion powder, salt, and olive oil (if using).
    Blend on high speed for 45–60 seconds. Scrape down the sides.
  • Refine Texture
    Blend again until silky smooth. Add more liquid 1 tablespoon at a time if too thick.
    For a warm sauce, transfer to a saucepan and heat gently over low, stirring constantly.

Notes

Cooking Tips

  • For maximum smoothness, always soak cashews well and use a strong blender.
  • Start with less liquid and thin gradually - small changes have a big impact.
  • Don’t overblend without pauses; excess heat can dull the flavor.
  • Stir in warm water if the sauce thickens after refrigerating.
