Kinda apples and oranges. (imho)only thing better is Scrapple,,,just do not read the label.
When I want a shelf stable ham "product" then SPAM works and is compact, (a dry, salt cured ham is better for flavor but comes in a bigger, single piece), dry cured bacon works great when I want bacon...,
but when I want scrapple or fried liver pudding, then those are what I want.
THEN there's braunschweiger (liver wurst)....and blood pudding...,
So you're quite right about not asking what's in the sausages nor in the scrapple...
