Melt butter in a sauce pot on high heat. Add sesame seeds and cook until butter begins to brown, stirring constantly. (Butter should turn a dark caramel color). Remove from heat and place the caramelized butter in a small bowl for later. Using the same pot you just browned your butter in, add rice, water and salt. Bring to a boil and reduce to simmer for 30 -40 minutes, depending upon the type of rice you use. Rice is done when all liquid is absorbed. Stir in butter and sesame mixture. Salt to taste.
