I love sweet tea... it's really the only way tea is good!
I use filtered water to keep my tea from being cloudy.. put it in my biggest pan.. Put the pan on the stove and begin heating the water.. when it is pretty hot I add in the sugar.. a cup at least.. Stir it up so that the sugar is desolved, and then put 4 family size tea bags into the water.. tuck the tags under a rubber band that's wound around the handle of my pan..
Bring it almost to a boil.. Then I put the lid on, set it over to the other part of the stove and let it steep and cool down.. once cool I pour it into a 1 gallon jug, finish filling up the jar with more filtered water, put the lid on tightly, put it in the fridge..
It will last us a three or four days and stays nice and clear... The filtered water is what keeps it clear, we have too many minerals in the water here.
