EMERGENCY BISCUIT FOOD RATION 20 year shelf life.

This is a typical compressed biscuit ration similar to the Lifeboat Rations, but made for the civilian market. It's marketed through alibaba, and is perfect to carry in your car first aid kit or even to take backpacking. The 100g block contains 450kcals and has all the electrolytes you need to keep you replenished for a short time, and is very nice as a snack. This option is described as being like cookie dough, but is just like a regular crumbly biscuit, and has a nice buttery sweet flavour. You'll have to wait a long time to see if it still tastes good after 20 years though.
