The premier artificial food product. A distant cousin of spam and vienna sausage.
Potted meat contains: beef tripe, mechanically separated chicken, partially defatted beef fatty tissue (how does one de-fat fat?), meat broth (note the careful use of "meat," so as to not constrain it to any one animal), vinegar, and sodium nitrite.
There aren't enough letters in the alphabet to put potted meat on the grading scale. I wouldn't feed it to my pet fungus.
