I am responsible for leg of lamb for Easter Dinner. I will cook the lamb
at my house. The meal is about 1 1/2 hours drive from my house. I'd like
to have the lamb hot at serving time, and yet not spend the entire
cooking time waiting for dinner at the place where the meal will be
served. Is it possible/safe to partially precook the lamb at my house,
drive to the meal and final cook the lamb there?

Any suggestions about how to do this? How far do you precook it (temp)?

Thanks
