When I was a student, I used to work at a breakfast cafe called "Riley's" which was run by a married couple who had met at and graduated from The Culinary Institute. This is how they made their Turtle Pie, hence the name. (Plan ahead - while it only takes a few minutes to complete each step, there is freezing time between each part. The prep time given is approx including the total freezing time.) I had to guess on the measurements - I usually buy a container of each ingredient and just pour out the amounts as needed.
