I don't know if anyone else has ever thought of this before, but I just had this little lightbulb go off in my head. I wanted to make some iced tea, and normally, I would boil the water and steep tea bags in it. I wanted a good container that could withstand the boiling water, and I happened to see an empty mason jar on my counter, with just the ring part of the lid. I thought, "Aha!", I can put it in the mason jar. And better yet, I can keep the tea bag tags on the outside of the jar by screwing the ring part of the lid over the strings! Voila! Perfecto!
