You must’ve eaten it straight out of the can.
It’s not all that different from some of the pressed hams like DAK, it’s pork shoulder. Not an inferior cut but it’s pressed.
Slice it, not too thick and not too thin, a little trial and error there. Then throw it in the skillet and fry it until crispy around the edges. Seasonings that work with a baked ham sit well with spam. Pineapple, or mustard, Or spice it up with a little heat.
Depending on how you season and prepare it, it works with eggs, it works as a hash with diced potatoes and onion, and it’s very popular as a variation on sushi, Hawaiians love it, consider it a delicacy. Plain old fried with hot mustard between two slices of bread is best to me.
It’s a very decent emergency staple with a shelf life measured in decades with proper storage. That’s reason enough to try to learn to like it.
Did. Nasty stuff.
