1. Cook rice and then cool it.

2. Grate cucumber into fine pieces. Chop grapes into fine pieces. Remove the seeds from pomegranate. Keep them aside.

3. Add yogurt,milk into rice. Mix well. If it's not sufficient then you can put some more yogurt (your estimation).

4. Heat 1 tsp oil in a pan and put cumin,mustard seeds and red chilies (cut into small pieces). When the seeds pop, remove from heat and add them to the above curd-rice mix.

5. Then put all the fruits into curd-rice and some salt to taste. Mix well.

PS: If you put the above mix for a long time 2/3 hours then the rice might soak all the yogurt and it becomes dry. So you can put some more yogurt, little milk to make it perfect. Don't forget to add salt also.
