Damn, (that first picture) I thought I was having a flash back to my early days on ship in the Navy - "Shit on a Shingle". Second look I saw what the kid was talking about, "bear grease". Sorry Jon. .
SOS was either red or white, depending on whether it was "Chipped Beef on Toast" or "Creamed Beef on Toast". I don't remember it being pink.... I liked the red stuff and sometimes make a "sorta" recipe I found on line.
