a lot of the recipes for chinese dishes call for oyster sauce & it’s pretty potent. many recipes i see mix soy sauce, oyster sauce and brown sugar together along with a tablespoon of cornstarch to marinate beef in for about 1/2 hr or so in a zip loc bag. i marinated sliced beef for more than 1/2 hour and didn’t seem to hurt it but it sure was tender when i stir fried it with broccoli
yum, I’ll give it a try!
