A lunchbox favorite with my children, this easy dish is delicious, inexpensive to make, and quick to disappear. A Spam musubi mold makes life easier, but it's not absolutely necessary. I have seen this made with a Spam can that has been cut on both ends, and it can also be done with a simple sushi rolling mat. The molds are inexpensive and can be ordered through Amazon.
2 cups of short-grain rice, cooked according to your rice cooker's instructions (brown rice can be used)
1 can of Spam (I use low sodium)
4 sheets of nori, cut in half lengthwise
Get your workstation ready by laying out a stack of nori, a bowl of cooked rice, a small bowl of water (to dip the top of the musubi mold into so the rice doesn't stick)
Slice Spam in approximate 1/4-inch slices, this should give you about 8 equal pieces
Brown in skillet
Sprinkle one side with a little sugar (approximately 1/4 teaspoon, but I just eyeball it)
Drizzle each piece with a little soy sauce
Place the pan of cooked Spam near your workstation
Lay out one piece of nori, place the tube portion of your musubi mold in the center
Put approximately 1 1/2 tablespoons of rice into the mold
Wet the top of the mold and then press down on the rice, to make it flat and even inside the mold
Place a slice of Spam in the mold on top of the first rice layer
Put another 1 1/2 tablespoons of rice in mold, and flatten again with the top which has been dipped in water again.
With the top still pushing down on the top layer of rice, lift up the tube portion
Starting at the bottom of the nori, fold it up over the rice and Spam
Roll until it is completely covered and then seal the end by rubbing a cooked grain of rice along the edge to act as the "glue"
When all of the Spam musubi have been assembled, slice into four even pieces
