But my favourite use for them is refrigerator ice tea. Add two tea bags and cold fresh water to a mason jar, replace lid and put in the fridge overnight. Voila! The next day you have nice cold iced tea for pennies a glass. Add sugar, lemon or leave plain. Whatever your preference. If you have a teenage boy like I do who guzzles drinks like there is no tomorrow than this is a nice replacement for store bought drinks.
