Some of my earlies memories were of Grand mom, and then mom, telling me about shortages in the first and second world wars respectively. Things were rationed and one needed ration cards to get most things, like tea, coffee, sugar, you name it. And money was tight to. People would make pants from grain bags, and bread and dripping, was popular. I have tried it, growing up dirt poor here in the south of the US. With inflation and supply shortages from the Covid mandate flow-on, and now war, I would not be surprised to find ourselves, we the already poor, back to bread and dripping.
