Liver wasn't specific. I'll knock out some fried Chicken livers but that's about it. No to beef, pig, or any other.
Same with snails, I guess fried conch fritters count, right?
Blue Cheese I like on something (good bacon blue cheeseburger), not as a dipping sauce.
My definite no's:
Cottage Cheese
Sardines
Beets
Tofu
Canned Tuna
Black Licorice
