I like unsweetened iced tea also. When my son, raised in Texas, came to visit me after I had moved back to California, ordered tea in a San Francisco restaurant, he was shocked when they brought him a cup of hot tea. LOL. Asking for Dr. Pepper will get you a funny look.
Fun fact: summers in Texas are so hot we make instant sun tea. :-)
I miss making sun tea. Are supposed to be done in Bakersfield in about a half hour. Here it takes all day. It feels hot but it’s mainly the humidity.
