I've read where you can put a pinch of baking soda in, to give it a darker color and cut a little of the bitterness.
The pguy makes the best tea, it tastes as good as you can get in a BBQ restaurant here. He uses 2 family size bags, and uses the coffee maker...8 cups (a pot). One cup of sugar, add water to make a gallon.
I'm thinking about changing to Splenda, the *sneekie* way...hum...wonder if I can bait and switch? Sure would be good for the health, and the waistline!
I do know that keep the tea on the heat for too long will make it bitter. Yours sounds good and right, too, Anna!
