Wash the rice in 2-3 changes of water. In a pressure cooker bring the 2-1/2 cups of water to a boil and add the washed rice. Don't add any salt.

Cover the cooker, place the weight and on full heat cook for 5-6 whistles.

Reduce heat completely to a simmer and let the rice cook for 25 minutes. Turn off the heat and let the pressure cooker cool down.

When the weight (whistle) comes off easily, open, fluff up the rice with a fork and keep aside.
