You learn something new every day, or so the old saying would have us believe. What I learned today (well, a few days ago) is that there's a type of soup made with green tea.
It's called Ochazuke and it's popular in - you guessed it - Japan. Apparently the two standard ingredients in Ochazuke are green tea and rice, which are livened up with assorted and sundry others, depending on the preferences of the chef.
For a little more info on Ochazuke, check out this brief piece over at O-Cha.net. While you're there, be sure to take a look around. The page is a production of the Japan-based World Green Tea Association and they've got plenty of information there on green tea. Maybe you'll learn something new today.
