Cram

 is a food item that restores some Hit Points but also gives you a small amount of radiation.

Locations
Cram is usually found in refrigerators. It is otherwise found in containers or on shelves. You get some Cram with the pre-War theme for My Megaton home or My Tenpenny Tower suite, but the amount differs for each one.
