My husband's grandmother who passed away a long time ago use to make this butterscotch pie. This was a HUGE tradition in their family and I hope to continue this tradition for the Holidays for them. Perfect Practice makes Perfect! It can be a little tricky to get the right texture/thickness of your liking. I've undercooked (runny!) and I've overcooked (wayyyyyyy tooooo thick!). I haven't really "timed" how long I cook the mixture to be honest, I just now go by how thick it's feels and looks when I'm stirring it. Good luck and let me know your results??!?? Warning: it does take some time to cook! A good butterscoth pie can be time consuming :-). Enjoy!!
