The instructions I received with this tea was that you place two pearls in the hot water but you can safely use one.
The fragrance from the bud is divine as it is so floral you would swear the flowers themselves were sealed inside. But be warned, that lovely welcoming scent fades and settles after a month or so of storage so seal them up as best you can.
As for the exact brewing temp I can’t say but I will say that these gems take a very short steep. The liquid is pale but that fragrance! I have tried similar flowers from the Republic of Tea who’s look and opening seduction was the same but the tea itself is a true tribute to the wonders of nature. It as if the that cup was what that flower had so longed to become and it is as jasmine goes very charming. I would leave the flowering bud to rest about a minute to two but much longer and the bitterness of the green begins to say hello.
Although purchasing these dainties from over seas may cost a pretty penny, I can run about my day and get 4 to 5 good steeps out of them. The fragrance diminishes but they still hang on to their exquisite green tea.
