When doing a mixed container, I put the Ziploc bag with various condiments from Taco Bell and other places, salt, pepper, hot sauce soup mixes and lots of things which can be put in the cracks and crevices in there. Also, put in the Ziploc with matches( in a small spice bottle) a couple of boxcutters and a manual can opener. Sam’s had tomato sauce, crushed tomatoes, etc. for three dollars and change per #10 can.
Freeze-dried food is nothing new. As early as the 13th century, the ancient Quechua and Aymara people of Bolivia and Peru pioneered a form of the process by exposing potatoes to the freezing temperatures of the Andes overnight, then drying them in the sun. In 1937, Nestlé used industrial technology to create the world’s first freeze-dried coffee, and in the 60s and 70s, the US military shipped freeze-dried food rations to the troops in Vietnam.
