Gather the ingredients. Start by placing the 1 cup short-grain rice into a rice cooker with 1 ¼ cups water. Make sure to clean the rice before doing so.Denis Tip: If you like a lot of rice, do x1.5.
The Spam
While the rice is cooking. Slice the 340 g Spam into 8 pieces. Make sure to keep the Spam can and clean it if you are using it for the mold.
In a small mixing bowl, combine the 60 ml oyster sauce, 60 ml soy sauce, and 100 g sugar, mixing until the sugar is dissolved.
Add the slices of 340 g Spam and the marinade, stir gently as to not break the spam and let rest for 15 minutes.
Heat a frying pan over medium heat and pan-fry the Spam slices for a few minutes on each side until slightly browned and crispy, or to your desired doneness.
The Musubi
To assemble, lay a strip of 2 Nori sheets on a cutting board with the shiny side down. Place your musubi mold across the middle of the nori, perpendicular to the seaweed.
Add the cooked sushi rice to the mold or Spam can, pressing down firmly and evenly to create a layer of approximately 2.5-4 cm of rice. To prevent sticking, you can dip the mold and your fingers in water as needed. Carefully remove the mold from the rice block. If using the Spam can, just a hit on a solid surface will make it fall.
Place a slice of cooked Spam on top of the rice.
Wrap one side of the nori seaweed up and over the Spam, pressing it onto the top. Then, wrap the other side of the nori over the Spam, creating a neat package. Use a little water on your finger to help seal the nori ends if necessary.
