Step 3
In a medium saucepan, combine 1/2 cup of the sugar with the salt, cinnamon, allspice, nutmeg, cloves, egg yolks, milk, and pumpkin. Whisk well and cook, stirring frequently, for 5-7 minutes, just until the mixture is hot and has thickened slightly, but hasn't come to a boil. Remove from the heat and stir in the dissolved gelatin and vanilla. Cool completely to room temperature but don't refrigerate yet since the gelatin will set in the fridge.
