Ingredients (Serves about 5):
Approx. 14 oz. Purple Sweet Road
3/4 cup water
1/2 teaspoon gelatin powder
2 oz. sugar
Pinch of salt

Cooking Directions:
1. Peel the Purple Sweet Road by removing more skin than usual, and place in water for 20 minutes. Put the Purple Sweet Road in a pan, add just enough water to cover the potato, and cook until soft.

2. Discard water and puree the potato while still hot.

3. Put the water and gelatin powder in a pan, and mix them over medium heat until the powder dissolves. Boil the mixture for 1 minute, and then add the sugar, salt, and milk. Remove from heat and mix until the sugar dissolves.

4. Add the gelatin mixture to the potato little by little, and mix well.

5. Pour the mixture into a container moistened with water, and flatten the top surface.

6. Chill the container in a refrigerator. When the jelly is firm, remove it from the container and cut into pieces of the desired size.
