Step 1: What's needed:
1/2 cup sugar (brown sugar gives a different taste).
2 1/4 teaspoons unflavored gelatin. (Most grocery stores carry it, but sometimes try to hide it)
2 heaping tablespoons unsweetened chocolate.
3 teaspoons warm water to bloom gelatin.
Vanilla extract (to taste) (equivalent of 1/2 half vanilla bean)
2 quart saucepan
Heatproof stirring spoon.
Small bowl to bloom gelatin.
Heatproof bowl large enough to hold jello mixture. (sometimes I just put the saucepan in the fridge to save washing items.)
Optional: Instant thermometer
