In a saucepan, cover the cashews with water and bring to a bowl over medium heat. Allow to boil for 10 minutes
Drain the cashews and place in a blender. Add the rest of the ingredients and blend on high for 2 minute or until it becomes a completely smooth liquid.
Transfer to an airtight container and refrigerate.
Spoon on homemade pizza just before cooking. Cheese will solidify as it cooks on the pizza and will taste just like mozzarella when eaten.
Leftover cheese can be refrigerated for up to two weeks.
