This works great with Campbell Farms Gourmet Popcorn Rice, but will also work with any white rice. I suppose it will work with brown or wild rice, but not sure. The 'Rice' button on your microwave is kinda in charge of it. At any rate, this works great at our house - no clumps, perfectly cooked.1 cup of ricebuttersaltwaterPour 2 cups water into a round 9" glass bowl with lid. Add a teaspoon of salt (maybe a little more - usually I just pour some in the palm of my hand) and stir it in. Then lay 4-5 pieces of butter on top. Put it in the microwave and push the Rice button. After cooking, let rest for at least 5 minutes with the lid on - DO NOT STIR because this will release the starches, and that is often what makes the rice clumpy.
