There's a commercial on the air in the U.S. for Jimmy Dean brand sausage. Now, understand, a guy who may or may not be part of the Dean family gets up in some commercials sometimes and plays the role of Jimmy.
At any rate, the commercial is for the latest breakfast products, including "biscuits" or "muffins" with egg and sausage.
Now, if you think sawdust is bad, check out the tag line: "The eggs come from real chickens The cheese comes from real cows. The sausage comes from Jimmy Dean."
As an American with among the most selective of palates, I will go so far as to comment that I'm glad somebody eats knuckles or feet or tongue or tripe, because I don't. I used to think pepperoni and sausage were my big concessions to nasty food, but it turns out the "sausage" I eat is nothing more than pork hamburger. I still don't know what all is in the pepperoni. I've identified fennel and bone before, but generally try not to push it.
However, there is a phenomenon among white people in the U.S. It amazes me how many of them claim to like chorizo. Myself, I can't stand the stuff. Not the taste, not the smell, nothing. And then one day I was in a supermarket in Oregon when I saw a roll of chorizo, picked it up, and made the mistake of reading the ingredients' list. Lymph and snout.
And no, I don't eat bratwurst. And a photo of andouille sausage in a "gourmet" cookbook (two volumes, I forget the price) reminds me of why I don't eat that stuff.
However, in the end, it's all snobbery. In the pseudo-environmental fight in the U.S., liberals often remind that "the native Americans used all the animal". So do we modern Americans. Horses become glue, sheep tennis rackets, &c. My jacket is made of some sort of animal, too. But I must admit that without a bunch of Mexican immigrant laborers I don't know what I'd do with pig lymph. To be honest, I'm such a snob it never occurred to me before.
But even liver is reviled on our beloved Turtle Island. Or whatever we call this place for PC's sake.
