1. Place the bowl for your standing mixer in the refrigerator before making the heavy cream/coconut cream layer. It helps keep all the ingredients cold. 2. I don't recommend making the purees too far in advance of making the popsicles. The purees (especially peach and cherry purees) change color if you don't freeze. 3. When you layer the purees, don't stress too much about them being perfect. Just have fun and know that they'll all turn out a little different.
