Your first clue that the sauce was OK.... it is in a plastic bottle, no? it was not swollen? it had never been opened? the seal was still in place, unbroken?
and it smelled and tasted good... use it! but then yes, once opened, keep an eye on it. In this particular case because of the ingredients... it will, in all probability, be good til you make your wings again.
I've lived in this house for over 10 years now, I just bought a new bottle of ketchup. I believe I had that bottle for about 6 years before I moved here.
AND I don't keep it in the fridge! It is in the cupboard, always has been.
But for some peculiar reason I keep my Chili Sauce and yellow mustard in the fridge, along with the different Dijon's. Weird. Don't know why, has no more reason to be there than the ketchup.
HP and A1 are in the cupboard along with all my Asian sauces.
