This tasty mincemeat mixture makes enough filling for close to a dozen pies, but you can make one or more as you want them and refrigerate the unused filling until needed.
Simmer all ingredients, except pastry, very slowly until cooked (about 2 hours), stirring frequently to prevent sticking. Line pie plate with crust. Add filling (between 2 and 2-½ cups per pie). Cover with top crust. Bake at 450 degrees F for 15 minutes, then at 350 degrees F for 30 minutes.
