I heard about the beginning of margarine. Mom tried it and rejected it. Luckily we lived in dairy country and I have only tasted margarine a couple time in my life.
They cooked with lard a lot back then. I use it to condition my BBQ grills.
Well, FWIW, lard makes the very best pie crust. Very flaky and delicious.
For many years we had home churned butter, later on mom bought some of the lard with coloring, we did use it cause we were so darned poor and no longer had a cow.
