The ideal method is to place your raw cashews in a bowl and just cover them with cool or cold water, and soak overnight. But, if you don't have the time, you can try the quick boil method: add the cashews to a small saucepan and cover with water. Bring to a boil and boil for 15 minutes.  If you have a high-powered blender and a small blender container (e.g., 32 ounces or smaller), you can also cover the cashews in boiling water for just 30 minutes. Whichever method you choose, be sure to drain the cloudy soaking water (it can be a little bitter and weird in color) and rinse your cashews in fresh water.
