Place water, cashews, lime juice and vinegar into a blender and blend until smooth.
Add chili powder, cumin, garlic powder and salt. Blend again until mixed well.
Notes
It’s best to soak cashews over night but if in a hurry you can soak in hot water for 2-3 hours or boil for 30 minutes. You can also grind them dry with a coffee or spice grinder.
This makes about 2 cups sauce. Serving size is 2 tablespoons.
