I am rating this 5 stars based on the raving reviews I get every time I make this pie :-) (I do not eat sweets but often have to make them for others!) this is a commonly requested pie at my husbands work functions and last night I made it more diabetic friendly by using Ideal sweetener in place of sugar. The one thing I do change is that I do not use the shortbread crust. I use slivered almonds that I crush a little by hand, add sugar and softened butter. I press that into the bottom of a pie plate and bake at 350 until lightly browned (depending on the oven 15-25 minutes) and when cooled I dump the filling in and continue as the recipe says.
