If you’re using a high-speed blender:
Blend all ingredients together in a high-speed blender. Start with 2 tbsp of almond milk and use the tamp to try to get the mixture going without adding too much liquid: you want an ice cream, not a smoothie! If you need the extra two tablespoons, use them, but be patient and keep blending with the tamp till a thick consistency is achieved.
If you’re using a food processor:
Soak cashews for at least 4 hours before prep. Place bananas in a food processor and let the motor run till they’ve turned into soft serve. Be patient. It takes a minute or two, and the processor sounds like it’s going to break. It won’t. Keep going. When you have soft serve, add the blueberries, powdered ginger, cashes, and lemon, and blend till totally smooth. Add the almond milk only if you need a thinner consistency; you may not.
You can store the mixture in your freezer and give it a whirl in the processor or the blender before serving; if you don’t, it’ll be a little “frosty,” but if you do, it will seem as though you just prepared it!
Re-blended it and served it as new
