i'm terrible for ignoring sell-by dates -i find that if it looks ok, smells ok, tastes ok, then it is ok!! mincemeat has sugar in which acts as a preservative so like jam or marmalade it really does last for years
No sell by date so they must be really old. I will probably end up erring on the safe side and throwing them away but I had the feeling mincemeat probably lasts for years.
Well I know that from our experience that Vegetarian MM, will keep for 18 months if sealed. But with proper Suet, I wouldn't chance it! But then, if it smells fine and shows no signs of fermenting!...
