Ok!
I picked up a lb, I'll try and do some research but 1/2# was what I was thinking.
Also, I've never used it before, I am going to be getting only sweetness or body & sweetness
A little of both. Just be careful, some people dont like lactose, so wohld suggest 1/4 lb to 1/2 lb at most then add if you want more.
Let me know what you think!
