  1. Place half the water in a large mixing bowl, and sprinkle the gelatin on top.  Set aside.
  2. Place the remaining water in a small pot, along with the granulated sugar, corn syrup, and salt.  Place the pot over medium-high heat and cook, occasionally swirling the pot gently, until the syrup registers 240 degrees F on a candy thermometer.
  3. Carefully pour the hot syrup over the gelatin mixture, and whip on medium low speed for 2 minutes.
  4. Increase the speed to high, and continue to whip until the sauce becomes thick, shiny, and white.
  5. Stir in the vanilla bean paste and transfer to a large mason jar.
