HAH I thought of you when I passed a can of Carnation in the store. Haven't noticed it for 50 years
My brd machine book tells me that pow milk creates a lighter texture crumb. I do use it but also, successfully I think, sub liquid milk for some of the water instead.
Occasionally I scald the milk as I am a little concerned with enzymes killing the yeast. Sometimes I don't and maybe that's why sometimes, it's not perfect.
