1. Depending on the quality and age of the brown basmati rice, it may take upto 25-30 minutes under pressure. Keep a timer for 25 minutes and if the rice is not yet done (rice feels hard and water is still remaining) you can continue to cook it for another 5 minutes.
2. I used Mina brand of brown basmati that is available in Union Co-operative supermarket here in Dubai. You may use any brand of brown basmati for this recipe. You can also make it with regular white basmati rice in which case the ratio of rice to water will be 1:2 (for every 1 cup of rice, you need to use 2 cups of water/stock)
