Heat the butter and olive oil in a saucepan over medium heat. Add the minced garlic and cook, stirring constantly, for 1 minute. Add the rice and cook, stirring often so the rice doesn't stick to the pan, for 3-4 minutes. Add the chicken broth and season with sea salt and white pepper, to taste. Bring to a boil then reduce heat to medium low. Cover and let cook 20 minutes.
