Nut and seed milks are easy to make, and some are delicious.  Many of these are high in calcium with no cholesterol. 

Grind 1/2 cup raw nuts or seeds to a fine powder.  Leave in food processor or blender and add 1 cup of water, vanilla extract, honey or Saccharin.  Blend for five minutes.  Stop and add one more cup of water, then blend for five more minutes. 

Strain the milk with a colander lined with two sheets of cheesecloth.  Strain a second time.  This milk can be stored for about 4 to 5 days in the refrigerator.  Use the leftover nut fiber for a nutscrub in the shower, in baking, or in your compost pile.

Some delicious nuts to try are almonds, cashews and sesame seeds.
