Why Brown Basmati Rice Stays Crunchy in the Instant Pot

Hello!

i really love the Brown Bsmati Rice Pilaf with Spiced Beef and Green Beans recipe. The flavors are spectacular! My problem is that the rice is still crunchy at the end of the cooking time. I have made the recipe twice and the rice has been crunchy both times. The only change to the recipe was using one pound of beef instead of 8 oz. However, my friend also made the recipe as written with 8 oz. of beef, and the rice was crunchy. I’m perplexed. It is either not enough water or not long enough cookin time, or both. Please advise. I don’t want to abandon this recipe because its flavors are so good!
