Mince is mince Mike. It's named only by the meat from which it's made, eg pork mince, lamb mince, beef mince, etc.
Mincemeat is always the delicious concoction of peel, currants, raisins, sultanas, nuts, and suet,(vegetarian if you must) with added alcohol.
We make our own, as shop bought tends to be both, too sweet, and too fine in texture.
