I recently tried Pinkberry and found their style of frozen yogurt to be quite good. Its actually frozen yogurt, not pseudo ice cream so it tastes like real yogurt. It made me think about all the lousy so called frozen yogurt places I ate at over the years - TCBY, Columbo, etc. and how none of it was really yogurt just fake ice cream. Is it really hard to make real frozen yogurt? Does anyone know how to do this - is it just like ice cream only made with yogurt? And if I wanted to have it be like the soft serve you get from the machine, can I do this at home or do I need a big, expensive, commercial machine? Thanks for any help.
