> But the idea that tomato goes well with beef the whole world over is very interesting
I saved a beef stew I was making for twelve people once by adding tomato sauce.
Beef hardens if stewed incorrectly and tomato acid tenderises it again.
EDIT: removed incorrect information about store bought tomatoes.
I have a hard time believing that that weak an acid can have a noticeable effect vs just the extra cooking time. Sorry for being a skeptic :-) Most of the time I deal with beef either it's the particular chunk of meat I bought that day or marinating it in salt for over a day or just stewing it for a long amount of time.
