So I proceeded with my plan, went to davidstea and got little samples of some straight black teas. I made it this morning with the recommended 1 1/4 teaspoons + about 1/2 a teaspoon of the kenyan tinderet.
… and proceeded to clumsily spill most of it as soon as it was done. >.< (I was so proud of myself, too, for getting up early enough to have tea and breakfast before work…)
Fortunately, there was just enough left to wash down my breakfast, and to tell that it was delicious. Experiment successful! Next I’ll try the nepal black or the darjeeling…
