This isn’t the nice shepherd’s pie you make at home with wholesome ingredients from Safeway or Trader Joe’s. This offal from some rural british slaughterhouse mixed with god-knows-what and (under) baked into a crust. So basically food poisoning pie.
Brits like that stuff, hell I order my burger med rare.
Sounds awful!
Just like British sausages, they are called “bangers” for a reason
