We made broccoli rice for the first time in a while. For 2 cups of rice, I added 1 1/2 tbsp of triple-concentrated tsuyu (noodle soup base) and 1 tbsp of sake to cook it. The mild seasoning allows the natural flavor of the ingredients to shine through, delivering the umami directly. For a change of flavor, try it with salted kelp (shio kombu), sansho berries, or julienned ginger.
