>Two years ago we got a whole lamb (minus head), and simply roasted it over a fire of oak and hickory wood on a spit. It was at least 45 lbs I think (the memory fades, but it filled the entire space of the bottom of my refrigerator [took out the bottom shelf and the crisper drawers]; got it the day before we were cooking).
You say minus head. I must, though you don't mention it, assume it was also minus fleece and eviscerated. I mention this fine point because several years ago I did a series of monthly wine dinners with my good friend Denis Kelly. He did most of the wine stuff and I did most of the food stuff.
I decided I wanted to spit-roast some kids (no, not that kind, although I have felt like eviscerating and roasting *my* kids on several occasions.) I waited to see how many reservations came in and I ordered the kid. I picked it up and hung it in my walk-in.
Apparently a bunch of people wanted to roast kids - or at least eat them after they had been roasted. I got about 30 late reservations. I saw I wasn't going to have enough food. Called my kid guy and asked him if he had another slaughtered and, if so, could I have it. He said, "Yah, but..." I said fine I'll be there in 30 minutes.
Guess I should have waited for the part after the "but" - at least I would have been ready for what I found. I found a dead kid. Head on, guts in, hairy skin intact. He said he had waited for me and now had to leave immediately (it was late Friday afternoon) and I would have to deal with it.
Took it back and hung it in my gazebo behind my restaurant, put a sheet of plastic down and went at it. Skinned it, gutted it, decapitated it. It was a mess.
Gave me an appreciation for those who do this sort of thing on a regular basis. (During this same era I also performed all those functions on a deer on a fella's kitchen table. He wanted to watch.)
Anyway, the dinner went well and folks loved their kids.
