Let the rice simmer slowly slimy with water and without salt, this takes about 30 minutes.
For the applesauce, peel the apples and cut into small pieces. Boil with a little water in about 10 minutes until they are translucent. Possibly add a little cinnamon or sugar (I use liquid sweetener).
When the apples are done, puree them with a magic wand or strain them through a sieve and then mix with the rice.
