I love rooibos!!! I’m Chinese American, and my tiny, new high school had just one language class back when I was there: Chinese. I was the one student of Asian descent in the school, so I got along really well with the Chinese teacher. She was super sweet and we would brew tea together for my AP environmental science class that used the same room. Incidentally, most of the time we made rooibos tea! (▰˘◡˘▰) I guess I took it for granted that everyone knew about rooibos, so this conversation here is very interesting to me.
They usually add some sort of sweet leaf thing to make the butterfly pea tea more palatable. Like a tea blend. But the butterfly pea tea tastes ok for a quick brew when the colour hits like sunny sea blue.
As the brew time lengthens, its astringent properties become more apparent and the colour approaches indigo ink /dye. The best way to enjoy it would probably be a good fragrant flower tea blend with just a pinch of butterfly pea for the colour so you can get the best of both worlds.

I always liked tea, but after reading this i became a bit obsessed. I learned so much from this, and i love how they use the real tea names so i can search them. I did a bunch of research on teas, and i came across this tea called "Butterfly Pea". It is a tea made out of a beautiful blue flower, the tea color is the amazing blue color, also i found a tea called rooibos tea, it has such a pretty red color to it.
