Dampen the mold. Soften the gelatin in the water. In a bowl, combine the eggs and egg yolks and gradually beat in the sugar, lemon juice and zest. Set the bowl over a pan of simmering water and beat until the mixture is light and thick enough to leave a ribbon trail, 5-8 minutes. Take from the heat and beat until cool. Melt the gelatin; whisk into the lemon mixture.
