Well, I’m going to try cold brewing this, but I think this one is a miss. I had to add some honey to cut the licorice root taste (there’s hardly any licorice root in it, but the aftertaste just lingers for me). I think it might be the coriander that’s just not working for me.
The idea of hibiscus and rose is a lovely one. I could see rose petals working really well in Agua de Jamaica.
