I tossed the can on top of the roast and it cooked for about 9 hours. Guests were asked to comment on the tomatoes. All of us agreed that they were sweet with a very distinct tomato flavor - maybe reminiscent of sun dried. Still, the flavor may have been masked somewhat by onions and garlic. The tomatoes were peeled and surrounded by tomato sauce. Is that common? My can also included basil but the flavor was missing.
