@aleshanee I tried my hand at making Spam musubi last night. This comes from my immediate supervisor who is from Maui. Soon after he took the position, his wife made a bunch of it for the bus yard. I liked it mainly because it was a quick snack for being on the go... a Hawaiian energy bar, if you will.
First of all, I am terrible at making rice; at least it came out tender and not like trying to eat gravel. The Spam part came out okay... I made a sauce with rice vinegar, soy sauce and a little bit of agave syrup. It caramelized nicely and had great flavor. I thought the nori was overpowering and tough, mainly because I cut the sheets too big.
I put the ones we didn't eat away in little baggies in the fridge. Today, they were AMAZING! Just sitting overnight the flavors came together and the nori softened up a lot. The biggest surprise was that Mrs. Abcaines loves them. When I brought the Spam home she wrinkled her nose and I thought I was going to eat a bunch of musubi by myself.
I plan to improve my rice making and finding a mold for the rice. I will find some nori sheets that are less pungent (if that's possible) and cut the strips smaller. I don't think I will change how I do the Spam since that was the only thing that I wasn't disappointed with.
