For the Strawberry Gelèe, bloom the gelatin in ice-cold water for 4 minutes. Drain well and squeeze out excess water.
Mix the purée, Superpomme, and sugar in a saucepot and bring to a boil over high heat. Reduce the heat to low and add the diced strawberries to the sauce, cooking until the strawberries are tender, 2 to 3 minutes.
