I just made my first batch of this and it was pretty decent. Not amazing, but definitely palatable. I had one big cup in place of dinner; I expected to want more but it was surprisingly filling. I started with the base recipe and added a scoop of vanilla whey protein, plus about a quarter cup of frozen chopped spinach.

I was expecting to have more issues with storing or measuring out the frozen OJ concentrate, but I just opened it, scooped some out with a spoon, put the lid back on, and stood it up in my freezer.
