Bad Manners and Brimstone

I understand the original did use lard. Also GMIL was Church of the Brethren (Mennonite offshoot) and said sometimes she had used half lard or vegetable shortening, and half butter.

Fun fact, the purpose of the vinegar in the recipe is to keep the gluten strands in the dough short, making the pastry more flaky. The idea was to have all purpose flour behave more like low gluten pastry flour, in case you were out of pastry flour or didn't want to spend the extra $$$ for it. Apple cider or white vinegar works fine.
