It’s hard to read all the reports about greenhouse gases and the cow industry and not feel a pang of guilt every time you sit down to eat a burger. Beef stew had been in regular rotation in our house because it was so easy and cheap. Usually I would use a tough cut, like a shin, and stick that in the slow cooker all day, or put it on at midday on high when I was working from home. I would cook it until the meat would fall apart and the disc of bone would be left nestling somewhere in the centre of the stew, bare and pale.
