Wild Kool-aid is what I call my concoction of water, berry juice and a touch of sugar. For purists, you could also skip the water and sugar in favor of pure juice. To make a drink from your berries, collect them, wash them, and drain them for a few minutes. Mash them in a pot and bring the mixture to a brief boil to kill any bug-related pathogens. Chill and drink as is, or chill and dilute to make it go farther. For a field expedient version of berry juice, place the rinsed berries in a clean bandana. Close and twist the bandana, so that the berries are enclosed. Mash the bundle a little with your hands, and twist the bandana to squeeze out the juice. Repeat the mashing and twisting until the juice doesn't run anymore. Drink and enjoy.
