Since this has been my favorite since I was little, mom made the 'from scratch' ones for years. I always watched so I would know how to make it when I grew up. When I was about 12, she poured the scaled milk............over the top of her hand when the handle slipped a bit. I decided I'd never make this pie myself, for that reason. Also never asked her to make it again.
Then Bisquick came out with this years ago and I figured I'd try it. You can't tell the difference between this as the from scratch recipe with the dangerous scalded milk. I was on cloud nine and I have custard pie often.
