1. Measure the sugar into a bowl and set aside.
2. In a five- to six-quart pan, mix the pectin with the apple juice and stir until the pectin dissolves. Tint a light red. Place over high heat and stir until the mixture comes to a full rolling boil.
3. Add the sugar at once and return to a hard boil. Boil one minute, stirring constantly.
4. Remove the jelly from the heat and skim off the foam. Place a leaf in each of nine hot sterile glasses and pour jelly at once over the leaves in the glasses. The leaves will wilt but they give flavor to the jelly.
