Butterscotch pie filling (untested)

This recipe is written in fountain pen. In the upper right corner are the initials "M.H.", so the handwriting may belong to Grammy's paternal aunt Maggie Munce Hansen. I found another copy of this recipe written in Grammy's early handwriting (below).

Although the original title of the recipe says "pie", it appears that this recipe is for a "no bake" pie filling. No instructions for the pie crust are provided. I don't know if it is supposed to be put into a graham cracker pie crust or pre-baked pie shell. Until we test this recipe, we won't know for certain unless someone in the family remembers eating this recipe years ago.
