I once brought some IMP home to show the kids when they were small. One packet was lung, I opened it up and squeezed it upwards. The kids being little and ignorant of what they were doing, took bites of it cold. They ate them and came back for more, squealing with delight... or that might have been pain. I was both grossed out and horrified at the same time.
Jim, I liked the baked orange dessert. What I miss from the old canned rations is the tin of cheddar cheese. And the Deviled Ham too. Was great on the crackers.
