My Italian grandmother used to love tripe. Eels, too. My French Canadian grandmother loved blood sausage. YUCK! Barfing smilies all around for those foods!
We just got back from a trip to Hawaii. Obviously, we expected fish to be popular, but hadn't realized that raw or barely cooked fish was such a "thing". You actually have to order your ahi (tuna) cooked to a degree, like a steak. Luckily, we were all good sports about it, and my pickier kids were willing to give most things a try. DD27, OTOH, was in heaven--she loves raw ahi, and ate her weight in poke bowls. She wouldn't touch the Spam, though.
I suspect the Cracker Barrel kerfuffle will die down in a few weeks, when they realize that they only sell 4 fake sausage patties a week. Maybe they'll keep a bag in the freezer, just to have them, or quietly take them off the menu. Maybe people are really protesting the disappearance of the turkey sausage?
