When water comes to a boil, add the rice and reduce heat to medium. Cook over medium heat, uncovered, until the rice is cooked through and is almost mushy. Stir regularly to prevent sticking.
½ cup round grain rice, or sticky, medium grain glutinous rice
When most of the water has evaporated and the rice is soft and cooked through, add the olive oil and lemon juice if using. Mix to combine and serve in shallow bowls.
