- Wash the rice until the water runs clear. This takes longer than you think. Soak the rice for 30 minutes and then drain. Transfer to a rice cooker along with 1.5 cups water and cook. 
- While the rice is soaking and cooking, prepare your filling of choice. 
- For the Spicy Kimchi Tuna, heat a drizzle of sesame seed oil on medium heat. Once it’s warm, add the green onions, kimchi and a little bit of kimchi juice. Sauté for 3 minutes. Add the tuna and guchujang and mix until fully incorporated. Put into a bowl and set aside. 
- For the Salmon Furikake, mix all the ingredients together in a bowl and set aside. 
- Once the rice is done cooking, add a little bit of rice vinegar and sea salt and mix. Let the rice cool enough to be able to handle. 
- Wet your hands (I like to keep a bowl of water near by so I can constantly wet my hands) and scoop 1/4th cup rice into the palm of your hand. Make an indentation and place your filling of choice in the middle. Shape the rice around the filling into a triangle, ball, or cylinder shape. 
- Place a sheet of seaweed on the bottom. Usually you're supposed to use unflavored seaweed sheets that you cut into the desired sizes but I like to use seasoned seaweed. (1) Because I like the extra kick of flavor and (2) because you can buy seasoned seaweed in pre-cut packets. 
- Sprinkle the rice ball with your choice of rice seasoning (furikake). My personal favorites are nori komi furikake and salmon furikake. Serve with roasted seaweed sheets and pickled plums (umeboshi).
