I grant that they make a distinction between UK "baked beans" and US "pork and beans", but the dish called Heinz Baked Beans looked and tasted identical to Campbell's Pork and Beans. (Don't let the name fool you. YOU try and find the "pork"!)
I thought the beans, like black pudding, fried bread, and fried tomatoes, might be something that was served up specially for unsuspecting Americans. But my web research says you guys actually eat - and relish - all of them first thing in the morning, when I'm barely handling toast and coffee. Gad! You guys are tough!
BTW, filled jelly doughnuts are Bismarcks over here, too. Hence, the coffee break call: "Let's go sink the Bismarck!"
Yes, JFK said "Ich bin ein Berliner." Fortunately, he didn't visit Vienna.
