1. I used homemade chicken stock which was made with boiling a kilo of chicken parts (spare pieces available in the supermarket) with 3 litres of water, 1 large onion, 2-3 garlic cloves, 1 chopped carrot, and peppercorns. You can use readymade stock or even use plain water in which 2 stock cubes (bouillon) have been dissolved.
2. Arborio or risotto rice is available in most well stocked supermarkets in India and abroad. It resembles the Indian boiled rice but is whiter in color in comparison to the boiled rice which is pale/creamish.
