I worked in a prison. Inmates made sterno type heaters with toilet paper and heated their bookshelf like a griddle. Porters smuggled loaves of bread into a block and a cook would make something like a grilled cheese sandwich with ramen mixed with mayo and canned salmon. Then, they put it in a clean sock with a rope made from strips of fabric and slung it down the range or “fish” it from the top range to the lower. It was really impressive cooperation from people that don’t get along very well with others
I started putting mayo in my ramen to make the soup more creamy and stick to the noodles better. Not many positive experiences from that place.
