We love the show but it's a shame James Martin makes every recipe look so delicious and fairly easy to follow yet some ingredients hard to source such as calves liver (calves liver with onion gravy and mash April 13 2019 episode). We wanted to make this dish but can't find s butchers shop or supermarket which sells calves liver, even Waitrose. Come on James give us recipes with ingredients us everyday folk can find in the shops!
