First, let’s clear up the biggest rumor: Spam is not mystery meat from a sci-fi movie. According to the fine folks at Hormel, it’s a simple mix of pork shoulder and ham. That’s it. Two meats. No hooves, no lips, no regrets—at least from the ingredients list.
The rest is a magical potion of salt, water, sugar, and sodium nitrite (which gives it that zombie-proof pink color). Oh, and potato starch to bind it all together. So, basically, Spam is a ham sandwich that went to boot camp and learned to survive nuclear winter.
