I have never even tasted Spam, and I never will.
It’s actually pretty benign. Spam is short for spiced ham although it’s actually made from Pork picnic meat.
Basically it’s just coarse ground picnic meat, spiced with a small amount of gelatin added.
Sliced and fried it’s makes a pretty decent sandwich. Tastes an awful lot like those small Danish canned hams you used to see in the old days.
You might taste it if there’s ever another huge World War and meat is rationed.
One of the first things we learned to cook in Home Economics when I was a kid was fried Spam in barbecue sauce, on rice. It was actually pretty good. Spam had become popular with many people during- and in the years just after - WWII.
My first experience was 60 some years ago on an Explorer Scout camping trip and it seemed OK. Then I had it a few more times and it gradually became disgusting. Haven’t had in about 60 years. In WW II it was one of the main food aid items we gave to the Soviet Union. The Red Army pretty much ate its way across Eastern Europe on Spam.
