Rice patties or tikkis require boiled rice, the softer the rice, the easier it is to make tikkis. Add boiled corn mixed with it, boiled grade carrots, you can add grade boiled potatoes if you want. And you will need coriander leaves, ginger-garlic paste, oil, turmeric powder, mozzarella cheese cubes. If non-veg use finely chopped chicken sausage instead of corn. Rice tikki or patty will be ready in very little time.
