The first time I tried making this tea I got distracted and oversteeped it by 7+ minutes. Needless to say it was bitter.
A while later I tried it again with fresh leaves for about 4 minutes. It was very blueberry-ish. It could use more bergamot but still a good Earl Grey. I am thinking of mixing with with some double bergamot for MORE bergamot, or some EG cream because a creamy blueberry EG has to be awesome.
It is good with milk and some sugar helps bring out the blueberry. I might try an even shorter steep time to see if that keeps the bergamot from being overwhelmed by the blueberry.
