Yep, D and I are big fans of tamales. I just had a couple for lunch yesterday at a favorite little Mexican restaurant in P'cott Valley.
We do take them with us on camping trips. Since they are labor-intensive to produce we prepare many in advance, vacuum-pack them in pairs, and freeze them. Then, they are relatively easy to heat in camp. I've occasionally placed them in our "manifold oven" and had them ready en route.
[Note: We pulled off a dirt road into a BLM 'dispersed camping site' last year, and while we were deciding which way to swing 'Harry' another vehicle stopped to ask a question. As he was in the middle of his question he sniffed the air and said, "Smells like there's a kitchen nearby." I confessed to the presence of a quick supper, and you could just see his salivary glands working. Unfortunately, I had placed only two tamales to heat, and we have our limits when it comes to hospitality—especially when it comes to our tamales.]
