I've been using this recipe for so long that I don't remember where it came from. I do remember that I'm asked to bake 3 pies every Thanksgiving. Two are for the dinner and the third one is for my sister's partner who demands a whole pie for himself.
2PIE: In a large bowl, combine lemon juice and apples; toss until well coated. Stir in sugar, flour, cinnamon, and 1/8 t. salt; mix well. Turn into a 9 inch unbaked pie shell. Cover edges of the pie shell with aluminum foil. Bake for 20 minutes.
3TOPPING: Melt morsels and butter over hot (not boiling)water or in microwave; stir until smooth. Remove from heat; stir in flour and remaining 1/8 t. salt. Blend until mixture forms large crumbs. Remove foil from pie. Crumble mixture over top of hot apples. Bake for another 25 minutes.
4I serve while still slightly warm with whipped cream or ala mode.
