the ingredients I used to try and make it called for pork sausage, liver, stock, and cornmeal. it was ok. just not what I wanted specifically. after you cook it and cool it hardens up and slices like polenta.
the ingredients on the stuff I buy read:
pork stock, pork, pork skins, corn meal, pork liver,wheat flour, pork fat, pork hearts, salt, spices.
mine doesn't seem too greasy. in fact I add a little butter to the pan because it doesn't have enough fat to keep from sticking. it does have a liver smell to it and some people can't stand that. to me the liver taste is what I like (though I can't stand straight liver). it isn' heavily spiced and I prefer it to breakfast sausage, much lighter fare.
