very interesting - although he is wrong to call immature potatoes green. Green potatoes are green because they have been exposed to light.
I have a lot of home grown potatoes and I will try adding some to my juices.
I have one of his books out from the library that has lots of recipes for juices it's great for someone like me who is new to it!! It was fun to read, too
Potatoe and green grapes very yummy together.
