My wife enjoys shepherds pie and uses a simple recipe. Pound of browned, ground meat, can of vegall, and fresh mashed potatoes. Good, but nothing special.
It has been made with beef, sausage, and bambi. Good, but nothing unusual.
Then I bought half a lamb. The same recipe with good ground lamb is simply outstanding.
I've put in an order for a whole lamb from the same farmer because it.has been excellent.
