There are two ways to make and enjoy tea. You can boil the water to the right temperature, measure your tea leaves carefully, time your infusions just right, all in the proper way. Your tea will be more or less good or bad. You’ll have the occasional great tea but will mostly find flaws.
Or you can forget the rules and simply make tea. It’s best enjoyed when you keep your mind empty and let the tea be whatever it is.
