Brown rice is a nutritional rock star in the rice family, however when cooked traditionally, it requires a long cooking time because the bran is a barrier to water. Significantly reduce the cooking time by using a pressure cooker.How to: Place 1 1/4 cups water and 1 cup uncooked long-grain brown rice in the pressure cooker. Close lid securely; bring to high pressure over high heat. Adjust heat to medium or level needed to maintain high pressure; cook 17 minutes. Remove from heat; release pressure through steam vent, or place cooker under cold running water to release pressure. Remove lid.
