Make it mince

I'VE JUST tucked into a delicious shepherd's pie, with garlic butter melting into the crispy potato on top.

I hadn't intended it to be quite so crispy but I put it into the Aga, poured myself a glass of wine and almost forgot about it.

We occasionally make it the day after we have had a roast leg of lamb. It's best made with cooked lamb and leftover gravy; it tastes quite different when it's made with raw minced lamb or beef - the latter apparently should be called cottage pie.
