Yorkshire puddings. Matzo ball soup. That extra bit of pork crackling on the side. “Cosy” can be applied to so many things; no wonder it’s the most overused word in food and travel writing every winter. But sometimes there’s no other way to describe a long-simmered ox-bone broth, apple strudel, or eating cheddar on the couch and watching Patriot Games for Harrison Ford’s knitwear.
