To be honest, I don't know but I'll ask her. I would assume around the same length of time that it says on the package (usually around 15 - 20 minutes for white rice and 40 - 45 minutes for brown). I would set my timer for slightly less than the target time and then start testing it. I don't see why it shouldn't be. I had the same issue until just this past year. I felt like rice was the one area in which my skills deserted me, but then I started paying careful attention to the proportions on the package and the cook time. You can always add more water, so better to be scant than generous. Ditto for time - set the time just a tad short. And I follow Molly Katzen's directive about not peeking - you can check once and that's it.
