Verjus Granite

Place the water and sugar in a saucepan and bring to a boil, stirring to dissolve the sugar. Remove from heat and stir in the Verjus and lemon juice. Let cool to room temperature. Place in a shallow container in the freezer. Stir every hour while the mixture is freezing to keep it homogenous, until it is a fairly thick slurry. To serve scrape the surface with a fork, creating large crystals.
