Summer and a hot one.
There are lots of ways to make ice cream-like stuff.
Blender, juicer, freezer, ice cream machine.
Use almond or soy milk in place of moo juice.
Add peanut butter (reconstituted peanut flour can work) or avocado or flax seeds or flax oil or omega-whatever (if you believe in those things) to smooth the final product.
Frozen fruits can also add "creaminess," especially in blender/masticating juicer ice cream.
