Spam musubi is hugely popular with high school kids around here. I was thinking of learning how to make it.

The soy and mirin is a nice touch. I learned using an old style spam can that could be open at both ends. the new cans only have a bead on the end you open. the musubi makers can be found online if that is preferred.
Prick two small holes in the bottom of the new style spam can, use some of the fat from the fried spam inside the can like one would a muffin tin. press the 3/4 inch of sticky rice into the bottom of the greased can, press in the slice of spam. Turn the can over and rap it squarely on the counter and a single musubi should pop out.
Think there will be musubi in the petro45acp house this weekend.
Cheers
