Imagine my surprise when I found this recipe. I have always known it as S. O. S. (Sh.. on a Shingle) even during my days with the Navy, we all called it that. In fact, I think I recall it actually being billed as that! I think Aggamat is actually egg gravy in Swedish. What ever it is called, it is still a quick, easy and inexpensive meal that fills the belly! Oh, and the recipe was dated 1912!
