We were introduced to these treasures when we visited a couple of years ago, and were sure to stock up on our first Tesco run. They're concentrated juices. Sounds simple, but they are YUM.MEE. They're really popular around here.
My recipe is 1 part juice to about 10 parts water. James gets a little bit crazier and goes for a ratio of around 1:7. And no added sugar, can't beat that! Well, they do have aspartame, which isn't the best, but you can't have everything.
