This is my daughter's favorite Thanksgiving Pie, but all my family loves it. When we are invited out for Thanksgiving, I am always asked if I wouldn't mind bringing this pie. Forget the custard type pies this one will win you over.
Beat Egg yolks and 1/2 cup sugar until thick, add pumpkin, milk, salt, and spices: Cook in double boiler until thick.
Soften gelatin in cold water; stir into hot mixture. Beat egg whites with 1/2 cup sugar until peaks form; add to pumpkin mixture folding in gently until completely combined.
Pour into cooled baked shell and chill.
If desired spread sweetened whipped cream over top of pie.
