Acorns make great prepper food, because most people have no idea how to make acorns edible. Almost no one looks at an acorn and thinks “food!” That’s because they aren’t edible until they’ve been processed properly.
A key skill for any prepper is growing and then preserving your own food. One of the most common results of manmade and natural disasters is an interruption in supply lines that fill those handy grocery stores. However, if you grow and store at least some of your own food, supply-line interruptions don’t have to be a concern.
Years ago, I planted a fruit cocktail tree—one of those trees that grows lots of different types of fruits. I managed to kill it off, except the roots. The roots shot up a beautiful peach tree. This last fall it finally had a full crop of peaches.
