Episode Details

Fish and chips may be the most British meal imaginable, but its story begins with Spanish and Portuguese Jewish immigrants who fried fish in olive oil so it could be eaten cold on the Sabbath. This deep dive traces how that tradition met the cheap chipped potatoes of northern England and became a national institution.

We explore the rival claims of Joseph Malin in London and John Lees in Lancashire, the trawlers and steam railways that fueled more than 35,000 shops by the 1930s, and why the British government kept fish and chips off the ration during both World Wars. Along the way we cover batter chemistry, regional condiments, and how the dish spread to Ireland, New Zealand, Australia and even northern Ohio.

• Why olive oil, not animal fat, made cold fried fish work for Jewish families observing Shabbat
• How North Sea trawling and the railway network created a nationwide fish and chip industry
• Why Churchill called fish and chips the good companions and wartime rationing spared them
• The science of crispy batter, beer batter and the Maillard reaction, plus scraps and chippy sauce
• How Malin's original recipe and fryers ended up with Arthur Treacher's, and how waste oil becomes biodiesel
