Well, I just tried to process the frozen yogurt, and it was a disaster! It got overly
frozen and hard with a thick layer on the sides of the bowl within a few minutes, and hence, the paddle had no room to turn. I was left with overly frozen, hard-as-a rock, icy yogurt on the bottom and sides, and mushy, liquidy stuff in the center. I'm very disappointed! My freezer was set at about 10 below, and that's what I usually use for ice cream - maybe it's too cold for this type of frozen concoction, since it doesn't have much fat, and therefore, is thinner and more watery than the typical ice cream. I used frozen strawberries, and David says frozen fruit can be used instead of fresh. I also strained the yogurt for several hours before using. What do you think went wrong?
Edited to add: I think I'll post this at egullet and maybe David will see it.
