It started as a joke and now my family does it too!
When it is cold outside and I don't feel like coffee or tea I just boil water and put it in a large mug The first time I asked my kids to make me one and they looked through the pantry for some "white tea". When they asked where it was I would tell them "when you put the hot water into a mug and look at it, it appears "white" to me." They would just roll their eyes, and now it's a big joke around our house. "Honey, would you like a mug of white tea with me?"
