Put the cold water in a small bowl and sprinkle the gelatin over it. Let it stand for about one minute to soften. Add the boiling water and stir until the gelatin is completely dissolved. The mixture should be clear. Stir together the sugar, cocoa and red chile in a small mixer bowl. Add the heavy cream and the vanilla. With a hand mixer beat at medium speed until stiff peaks form. Pour in the gelatin mixture and beat until well blended. Spoon into serving dishes. Chill for at least 2 hours.
