Legend has it that in 2737 BC, Shen Nung, the second emperor of China, discovered tea when leaves blew into his pot of boiling water. There are six main tea types – black, green, white, yellow, oolong and pu-erh – but they all come from one plant, Camelia sinensis.It’s how the leaves are treated that the different types of tea are created.
Spherifiion relies on the ability of calcium to cause alginate to gel. Excess calcium can prevent hydration and cause the liquid to gel prematurely. So it can be problematic if a liquid already contains calcium before you add Sphere Magic or alginate. For reverse spherifiion and frozen reverse spherifiion, the solution is to avoid using hard water when preparing the setting bath.
