Marilyn, you are not alone. It is not your fault. You have been the victim of an insidious and evil
advertising campaign by Minute Rice, with that scary bespectacled cooking teaching claiming your rice will be "perfect rice every time because," (writing in perfect penmanship on the chalkboard with a metal chalk-holder), "it is Never Boiled!" Who wouldn't be scared of rice after that? An entire generation is still reeling from the damage.
Hooey. Rice is supposed to boil, and it doesn't have to be perfect. Just put water and rice in a pan, 2 to 1, DON'T STIR, simmer slightly covered until there are steam holes on top and the liquid has retreated out of sight. Cover and let stand off heat until the rest of dinner is ready, then fluff with a fork. Using the same pan each time and the same temp, you may find you need to add a little more or a little less water to suit your conditions.
This doesn't help you with your Thai rice, I know, but I felt like ranting.
