So the follow up: What to pair with this teapot? I'm not familiar with Chao Zhou clay besides a very thin modern one I have from Tea Habitat. It's got pretty thick walls, so maybe something more roasted. Suggestions?
I think for a start, you should clean up the pot first.
You can do the search online quite easily on various method of cleaning it. I just say that you must NOT use any detergent or chemical to clean it, any natural way of cleaning is OK.
For tea pairing, for a Chaozhou pot, brew them with the tea Chaozhou people use. Typically there 2 types commonly used by them. They are rock tea e.g. Shuixian, Tie Loh Han, Da Hong Bao etc or the other is heavy baked or fired Tie Kwan Yin.
The traditional Chaozhou brewing method is an art by itself, it took me more than 10-20 years of religiously practice and experiment to just to understand it....we can talk for years on this topic. I have a Chaozhou set up "station" at home just to train on brewing Chaozhou style and did it very often for many years...and still learning everyday.
But not to worry. Just do it and a start is always the beginning of a great journey..So just start and try with these 2 teas and see how it goes.
Good luck and enjoy a good tea day my friend.
