So I grew up in the South making sun tea, we even had the special little glass jar with a spigot on the bottom just for making it. It was painted with little flowers and was super cheerful. Sun tea is so easy too, just add water, tea bags and let it sit in a sunny spot for a few hours. Then add sugar, lemon, or mint and you were done.
Now apparently, sun tea CAN KILL YOU!!! By not boiling the water you are allowing an environment where bacteria can grow and (it is implied) eat your face off, scare your dog and ruin your credit rating.
I live in a house without air conditioning, and boiling anything on my stove top add a certain humid heat that is unpleasant. I made some deviled eggs for the girls the other day and standing anywhere near the stove was what I imagine a wrinkled shirt feels like under the iron. I could make it in the microwave but I always forget it and then hours later I open the door to defrost something and BOOM there's a glass measuring cup full of cold tea staring at me.
What is a southern girl to do? Make some refrigerator tea, of course! Just add water and tea bags to a pitcher the night before and leave it in the fridge for 12 hours. The next day you will have fresh iced tea. To add sweetness to already cold tea, I simply make a cup or two of simple syrup and use it to sweeten individual glasses. Simple syrup is just 2 parts sugar to one part water, for instance if I boil up 2 cups of water, then I add in 4 C of sugar, stirring constantly. Once the sugar has dissolved I remove the water from the heat, let it sit and cool and thicken, then pour it into a clean mason jar and refrigerate it till I need it.
So there ya go. Of course you really need a refrigerator for this recipe and I won't have one until this weekend, but have a nice cold one for me!
