We had a successful Caja China pig roast last year and are planning another soon. I visited the web site
and found some changes: the instructions now have very clear photo illustrations for each step, there's a nice salsa audio track, AND they now offer a battery-powered spit so you can roast a whole animal above the coals rather than (or maybe even at the same time as?) inside the roasting box. I had been thinking about doing a whole lamb or kid but was concerned it wouldn't fit inside the box; the spit (which I've ordered) should solve this problem.
