It lasts until your fat uncle eats it.
No more than one week.
Just called the people who make Ken's Steak House dressing, the woman told me the dressing is good until the expiration date. I even asked if that was true for the creamy caesar (I dont't feel to good about that, has anchovy), she said yes!
It can normally last about three days after that,it is best to discard right away. This is generally due to the ingredients that consist of the dressing.
Homemade pimento cheese will remain fresh for up to 4 or 5 days in the refrigerator.
I've had salsa that I've heat processed in canning jars last about 2 months. Might have lasted longer if I hadn't eaten it.
That will depend upon the recipe, but I would think it should be cooked within a day or two.
