Create Spam Musubi:
Place a piece of plastic food wrap in the spam can. Pack portions of cooked Calrose rice in the spam can and cover the rice with food wrap. Use your fingers to tightly press down the rice. Remove wrapped rice from the spam can by pulling the food wrap upwards. Unwrap the rice and add a layer of Furikake.
Place a piece of browned spam slice on top of the rice and wrap a piece of nori around the rice. Use a few grains of rice as glue to seal the ends if necessary.
