I have to say I was surprised at a) how easy it was to make & b) how much nicer it was than the shop bought 'nut' milks. I will happily do it again. I have yet to try making my own rice milk, but I reckon cashew nut milk should be very good as well. I have the soya beans ready to try some homemade soya milk when we get back from out holiday as well. I did this
http://nouveauraw.com/raw-recipies/desserts/deep-dark-chocolate-blackberry-cheesecake/ recently as a birthday cake for myself which was excellent. You would never have known it was made from cashew nuts - but costs wise, it is definitely "a treat" - once a year job nothing more. It is on the menu again though because my brother-in-law is looking at opening a raw food café and we want him to feature it. We know it will be a hit.
The raw food diet my b-i-l is on works well for him. It makes him watch his diet. He is type 1 and has been able to reduce his insulin requirements by massive amounts. I can't say I understand it, I'm not diabetic (just seem to have most other things (severe asthmatic, with partial 2ndary Addison's diseases amongst many other issues, allergic to all dairy)) but it works for him. I have incorporated a raw diet into my lifestyle for decades simply because I love raw veg (as well as wild veg/leaves etc) and used to grow a lot of my own veg. It will soon be time for nettle harvesting again, which I love. - do get strange looks though standing around in wellies with marigold gloves on my hands, a pair of scissors and ... don't have our own nettle clump anymore

... shall have to have words with my landlady and see if she minds me exploring her land (12-15 acres) to see what I can find.
