Sliced into Spam and found firm white chunks embedded throughout
Spam is cooked inside the can during the production process, which causes the proteins and fats to set in place as they cool. This setting process can lead to the formation of solidified fat chunks.
The fat in the meat rises to the surface and solidifies as it cools, which can create the appearance of white spots. This is a natural occurrence in processed and cooked meats, especially those that are canned.
