Second post. I recently got dragooned into doing a hog roast for a mate. He called me at 11 on a Friday night and told me that he'd bought an 80 pound pig and had a spit made by a local blacksmith (we're horsey types, so blacksmiths are people we know). I have a bit of a rep as someone who can cook almost anything, and my mate can't even make tea, but I started the hog at ten thirty and my "friend" kept telling folk it would be ready by 7 that evening
. In the end I did sixteen hours, non-stop, and all I wanted at the end was a small salad and a glass of water.
I have a few of words of warning:
1. Get the pig well in advance: it needs to be at ambient temperature before it goes on the spit (overnight in the garage is fine, but straight out of the butchers cold-store is bad. It'll take six hours to get to temperature at the middle of the neck BEFORE it starts to cook.)
2. Make sure you have loads of good, well-seasoned wood on hand, or enough charcoal to keep a forge in business for a month. Running out of fuel is bad.
3. Score or prick the skin straight out of the cold-store. As soon as the skin dries it makes the job ten times harder.
4. If you have a manual spit make sure that there is someone to give the main cook a break, and give anyone who takes a turn turning the pig plenty to drink (and not just beer, as this can cause the chef to fall over.)
The above is hard earned experience, and the intelligent reader can gather what happened.
The spit was made by a local (Hampshire) smith, and cost about two hundred quid, but it's big enough to do two swine or four lambs at once. I'll see if I can get some photo's up, if someone can give me a few hints how to.
PS. My friend and I haven't spoken since, but I made a huge quantity of rillettes out of the leftovers, so I'm not complaining. He is, tho'
