What is the ratio of water to rice for white rice in jambalaya?

Long grained rice, including Jasmine and Basmati rice, is cooked, unwashed, in a ratio of 2:1, water:rice. Sushi and most other short grained rice is washed first, sometimes drained for up to a half hour, and sometimes soaked. Because of those processes, the rice requires less water, usually equal parts water and rice, or, perhaps a little more.

These instructions are specifically for a rice cooker. Rice cookers detect the temperature of the rice so that when the water almost completely boils off, the automatic cooker turns off. The steamed rice should remain in the cooker covered for at least ten minutes so that the remaining moisture is absorbed.
