On page 52 of the Healthy cooking magazine, June/July issue, I tried the Berry Patch Pie, however it didn't set up like a jello substance as the pictures shows, it was very runny/watery. Can you tell me why? I did cook the pie shell the night before & let it cool. After cooking the berries I did let it cool on the counter for about an hour, put in refrigerator after & still didn't set up. Help!! Please. Thank you Pat Thelen, Lansing Michigan
