Why don’t Americans eat mutton?
Mutton/lamb is the most delicious of all non-fish meats.I don't particularly love beef/chicken/pork but a sunday lamb roast with crispy potatoes and gravy - yum.BUT - cooking lamb well is an art and takes alot of practice.  You can't just go cook lamb any old way and think it will be delicious.  If you want to learn how to cook lamb well then focus on slow cooking and slow roasting - and anticipate you won't really knock people out with it until you've practiced enough.  Jamie Oliver has the best lamb roast recipes.Lamb leg is extremely cheap at the moment in Australia - $10/KG - so I am practicing my lamb leg roasting skills.
