Sugar is often used with salt in brines and meat-curing recipes. While the salt does most of the work to prevent spoilage, sugar can also hinder the growth of many bacteria that are responsible for food poisoning. Sugar is found in countless pickle recipes and preserves, as well as the traditional cured ham formula.
Sugar, water and yeast are all you need to create alcohol. Use a jug or some other container, filled with your fermentables and plugged with a wine lock. Then play the waiting game for the booze to form. You can use regular table sugar, or any other sugar to create your home brew masterpieces. For good tasting results, follow a home brew or home wine making recipe, and incorporate fruit, malt, or other brewing ingredients.
Come up with some potassium permanganate for your survival kit, add it to some sugar, and you'll have the makings of the easiest friction fire you've ever tried. Mix the dry sugar and the permanganate powder in almost equal portions. Use almost a teaspoon of sugar and a little more than a teaspoon of permanganate. Grind these two against a hard surface with a stick, and have your tinder standing by. Get the ratio right, generate enough friction, and you'll get enough of a reaction to light the tinder.
