Spam Musubi

Step 1
Soak uncooked rice in water to cover for 4 hours; drain and rinse.

Step 2
Bring 2 cups water to a boil in a medium saucepan. Add rice and stir. Reduce heat, cover, and simmer for 20 minutes.

Step 3
Remove pan from heat and stir in rice vinegar. Set aside to cool.

Step 4
Stir together sugar, soy sauce, and oyster sauce in a medium bowl until sugar is completely dissolved. Slice luncheon meat lengthwise into 10 slices, or to desired thickness, and marinate in sauce for 5 minutes.

Step 5
Heat oil in a large skillet over medium-high heat. Cook slices until lightly browned, about 2 minutes per side.

Step 6
Cut nori sheets in half and lay on a flat work surface. Place a rice press in the center of a sheet, and press rice tightly inside. Top with a slice of luncheon meat, and remove press. Wrap nori around rice, sealing edges with a small amount of water. (Rice may also be formed by hand in the shape of the meat slices and about 1-inch thick.)

Step 7
Serve musubi warm or chilled.
