Also, have plenty of unsweetened Koolaid (I like grape) stored away. You can find packages that make 2 quarts on sale sometimes for 10 cents each. Add 1 cup of sugar and you have a tasty drink that everyone (especially children) will enjoy.
Sugar opens other possibilities such as making alcohol for consumption, trade and can even be used for fuel. It has an almost unlimited storage life if kept dry.
Cut the recommended amount of sugar for the koolaid in half and it’s still tasty.
