Preheat oven to 425. Mix all ingredients and pour into unbaked pie shell. Bake for 15 minutes, reduce heat to 350 and bake for 40-50 minutes. Note that since this does not use eggs, a knife inserted will never come out clean. The pie will finish setting in the refrigerator as the gelatin congeals. Remove from oven and set on a wire rack to cool. Chill thoroughly before serving.
This should work with whatever kind of crust is safe for you.
