The Science of Spherifiion | ChefSteps
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.
