I'm the "pie lady" for my family, too. I typically make 4 or 5 pies for Thanksgiving - there are about 18 of us if you count the little ones. I always do 2 pumpkin pies and use my grandma's recipe from the 1930s. It's different from most pumpkin pie recipes in that it does not call for nutmeg - just cinnamon and a little ginger and vanilla. She taught me to use half-and-half in the recipe, so that's what I do. I also make chocolate pie (again, using some half-and-half instead of all milk for a great texture and richness) and either lemon, coconut, or key lime. Other times of the year, I make peanut butter pie and strawberry pie, both with store-bought graham cracker crusts. I make my own regular pie crust from scratch: butter, Crisco, flour, salt, and ice water.
The discussion on Key Lime Pie was absolutely right -- just 3 ingredients: key lime juice, egg yolks and sweetened condensed milk. I live in Northwest Florida and my friend has a key lime tree and shares the bounty with me. When she gives me a bunch, I juice them and freeze the juice in ice-cube trays so that I always have it available. I freeze the zest, too. I make key lime cookies for Christmas.
