You Are Raising A Teapot
The liquid from this rinse step is not consumed, and is discarded, before the first “true” steeping is made and then enjoyed. As my mother gifts me the chahu, she says that this one was made from the regional Taiwanese clay, which most producers increasingly use less of, as imported clays improve the bottom line as Taiwanese clay can require more steps and massaging to yield a desired finished result in the earthenware.
Save the rinse, she says, pour it over the chahu; always offer the chahu its first yield. She continues, 你在养茶壶; you are raising a teapot.
