The only tea ball I have tried is shaped like a tea pot. When the tea in it gets wet it swells up, and the tea just can't steep. It is cute but just does not work well. I like the pot with the removable mesh strainer. Do Not use a cheese grater if you have nothing else. Brilliant me, making tea with nothing to strain it with, decided the cheese grater was the answer. Well, bits of tea leaves and orange rind escaped into my cup, I drank it, and got the worst case of indigestion/heartburn ever in my whole life. This is a wonderful cinnamon spice tea with cloves and orange rind bits, my favorite, but it does not go well with pizza either.
