Basmati, finally restaurant good at home.

I have been deeply pleased with my newest attempt to cook basmati rice. I have been trying for years to cook it reasonably well, but I guess I haven't been looking in the right place for instructions. On the internet the other day, it was suggested that one should soak the rice for roughly half an hour. And during this time stir the rice to remove the starch and change the water three times. And then, using a regular rice cooker add the rice and new cold water in a 4 to 5 proportions. Add about a teaspoon of lime juice per cup of rice and about a teaspoon of butter. So a table spoon of lime and butter per three cup of raw rice. The rice cooker does the rest
