I put this on and in everything... Noodles, stir-frys, potatoes... cheesecakes. Hell, I've christened infants with the stuff.
I haven't tried many oyster sauces, and I probably don't know shit about them in terms of quality, but I still love this stuff, and I can even find it at Wally World, so I don't have to go to a specialty store to get it.
