Peanut Butter Ice Cream Pie

  When I lived in Battle Creek, Michigan, a summer destination was The Turkey Farm, a restaurant in the country that served various kinds of turkey dishes made from the birds raised on the premises.  But my favorite item on the menu was the peanut butter pie, a dessert that I had never heard of before going there but one that I quickly became fond of.
   Over the years I found various recipes but never any that I really liked all that much.  But that changed when a family friend, Marjean, brought her version to my dad's memorial service. (Yes, we are all about food in my family and when my dad died, we did all the cooking for the guests who showed up at the service.)
The taste and the texture were almost perfect...
   One thing that I find boring is a graham cracker crust.  Easy to make and done to death, it shows up in places where it should never have been invited.  And store-bought ones are the worst offenders unless you call a box of Jello pudding and a carton of Cool Whip baking..... I don't.  But I did like the recipe and thought it deserved something better than graham crackers and butter so I went online and in no time at all was greatly rewarded for the small effort.
  Anyone who worships desserts knows that Rose Levy Barenbaum is the queen of tarts.  Her strawberry cheese cake, which calls for lady fingers instead of the graham cracker crust, is a fluffy taste of heaven in each bite.  So, when looking for a peanut butter crust for this pie and coming across her recipe, I knew I was in for a scrumptious treat and I wasn't disappointed!
