Gravy and clam chowder do NOT have tomato in them. Tomatoes are anti-American.
I have many good friends on Federal Hill in Providence—fiercely pro-American, and yes the tomato based sauce is gravy. Suck it up and lick the drippings off your tie, it’s the best food and the most loyal friends you’ll ever find. And if you don’t agree, good luck to your family finding your body.
Just sayin’.
