Cactus fruit marmalade

1. Prickly pear fruits are cleaned carefully, doing the work with gloves and holding with a fork. Prickly pear pulp is crushed with a blender or rubbed through a sieve.
2. Add hot water to the agar-agar and mix until the lumps dissolve.
3. Put the ground cactus pulp into a saucepan, bring to a boil, and add sugar and agar-agar, mix and turn off.
4. Pour into a mold, I have it silicone. Marmalade with agar-agar hardens quickly enough. Cut into cubes and sprinkle with sugar.
