Aged large leaf loose puerh in a coconut. I had tried this tea with one of my roommates earlier; he had thought it tasted like coconut, and thought it might be better brewed with some actual coconut thrown in. Then later there was a coconut in the fridge that he had used specifically for the coconut water, and he offered the rest to me. So I had an idea...
I simply threw a few leaves at the bottom of the coconut, and poured in some boiling water, adding more boiling water as a drank, just as you would drinking a tea grandpa style. I thought that I wouldn't like drinking tea through a straw, but using it actually meant that I could drink the tea while it was still a little too hot without burning my mouth, as the tea cooled significantly in its passage up the straw.
The result was much better than I thought it would be, as the coconut and puerh played off themselves nicely, with neither overpowering the other. The tea also maintained a pretty nice qi, which I wasn't expecting from the method.
Who needs teapots anyways?
