Blend all ingredients in a mini food processor or blender until well combined.
Add salt/pepper to taste ( I didn't as the kombu and tamari were salty enough)
Store in glass jar in refrigerator for up to a week.
Kombu is dried sea kelp and can be found at Whole Foods, Wegman's and most Asian markets. You can even buy on Amazon for around $4!
If you don't have cashew cream, boil 1/2 cup raw cashews for 2o minutes and blend in a high speed blender with about 1/3 cup water.
