There's no Spam (the food) in the U.K.? We had that stuff when I was a kid. It tastes kind of good, but is also kind of nasty. It's really popular in the Philippines and the Pacific Islands.
It's a highly processed chunk of mystery meat. And when you open the can it's swimming in it's own jelly. An artery clogger to be sure. It's pretty sick, but it actually tastes ok, kind of like McDonald's.
