Iced tea made that way is called Sun Tea. My mom made tea by using tea leaves, not a bag. She would heat water and then steep tea in it. Then would strain the tea leaves out before adding the tea to a larger pitcher of water. She would add sugar and then pour into a large glass filled with ice. I can't stand sugar or lemon in ice tea. I don't like sweet tea. It's a battle when we eat out not to get sweet tea with lemon.
