Another old time thing is using preserves of any kind.
Like using jam or dried fruit in pies.
Raisin pie or mince meat pie kicks butt!!
The basic idea is make some kind of pie crust.
Fill it with nuts and hydrated dried fruits(hydrated with water , booze, or available frruit juices), perhaps suplimented with whatever fresh fruits or fruit juices are available--or already prepared jam or real mincemeat. If needed, cook the filling down, and perhaps add cornstarch or other stuff to thicken it. Add spices like cinnamon or allspice.
Dump that into the pie crust, maybe put some stuff like oatmeal, chopped nuts and sugar on top, and cook it.
Properly done, this is one of the most intensly flavored and tasty of deserts, especially if served with some sort of cream on top.
Drool.....
