Almond milk can be made in a blender. What I have heard works best is to soak the almonds in the water overnight, then puree in blender and strain through cheesecloth or coffee filter. The leftover ground almonds are good in recipes, too.
There is also the quick and dirty version: shake or blend almond butter and water until smooth. Good on cereal.
You can also make nut milk with almost any nut or seed.
