Quick Oyster Sauce Question
I rarely cook Chinese food, and have had an unopened (I think, it was completely full) bottle in my fridge for more than a year. I took out a tablespoon for a noodle recipe I want to make tonight. It smells kind of fermented, not fishy and mildly sweet. Is that how it's supposed to smell, or has it gone bad?
I've used open bottles that have been in the refrigerator for over a year and no problem.
If it was never opened and in the refrigerator it's probably fine. Could have a slightly fermented odor from the soy sauce in it because soy sauce is fermented and oyster sauce shouldn't be fishy smelling. I think it's so loaded with salt that's why it can't go bad especially if it's been kept in the refrigerator after opening. Like ketchup...never had a ketchup that's gone bad that's been in the refrigerator.
