I have been thinking about doing this when i get my vitamix, its very simple..
1 cup of raw almonds to 4 cups of filtered water, blend and strain..bam almond milk with no additives. you can make whatever flavor you want too. Once I get my vitamix im gonna do it! its almost 4 bucks a carton here and i got through one a day pretty much so If i could just make it myself it would be cheaper too!
if you make it yourself what do you add? id probably add a little sugar and vanilla bean or something, for just a little flavor.
I worked with a lady whos made her own almond milk for the last 20 years. Her only regret is it is so time consuming and requires extra work, and since she has developed a taste to homemade she has yet to find a store bought she likes, and wishes she could buy it to save time and money.
Almonds are like $6/pound here and a quart of almond milk is $3 and cheaper if I have a coupon so I don't know if it would really be worth it for me though i would love to try it. We were giving almond milk to our oldest when we thought cow milk was causing him problems.
