Jay:
Thanks for that link. That's exactly the information I've been looking for.
It seems to me that the method and recipes would work for goat, also. I live in a part of Spain that is famous for it's roast goat and lamb. Spaniards mostly roast the milk-fed babies (cordero lechal; cabrito), but now I think I'll ask my local butcher to track-down an older one.
I've also read in the LA Times recently that goat meat is becoming popular in California.
Josh Z.-- If you try this recipe with your lamb shoulder, please post your results. I'd be very interested.
