Don’t you remember ? I had filled my yuzu citrus with tea :
Now, the fruit peel is dried and hard, and the tea naturally perfumed. So that works. Just be patient, count one month. You can make yours with your favorite citrus peel.
The coloration is not uniform, not totally black, but well compared with the raw fruit…
How to use :
Break some bits of skin, put them in the teapot with some of the tea inside. Rinse very brief with hot water, pour some more to brew. Serve. Later, brew again 2 or 3 times.
