Yum! Rich and delicious flavour. Now I don't really have the right to rate this recipe as is because I didn't make it as is. How I altered it did work. Sometime I will try it as the original indicates, today just didn't have enough time. Here's what I did: 1/4 cup soy sauce instead of 1/2 cup 1/4 cup white sugar instead of 1/2 cup 11/2 tb red wine instead of Asian plum wine (I didn't have any!) Instead of marinating the beef I browned it in a non-stick frying pan and tossed it into my slow-cooker. I added the marinating ingredients to the hot frying pan and let it come to a boil to collect the drippings from the beef, let's face it, it's yummy even though also naughty! Then with everything in the slow-cooker, turned it on low for 6 hours and it was nice.
