As I read this I thought you must be Canadian! This is what my family has used for years. I have been having trouble finding decent lard in the USA and finally have had friends or family send it to me.
This recipe never fails and freezes well also.
Opps the 1 pound lard, 5 cups regular flour, the egg, water and vinegar in the cup I use a pastry cutter to blend lard and flour and then add the rest.
