Great, thanks! (I did ask my mum, but as she let me make and eat most of a ten-year old lemon meringue pie packet mix when I was a child, and was then shocked when I was very ill, I don't tend to trust her judgement on these things, so thought I'd ask the experts instead ).
I made some really delicious mincemeat last year, with apples, dried fruit, chopped nuts and lots of brandy . I've still got a jar left which hasn't been opened since it was first put in the sterile jar a year ago. Can I use it to make mince pies now or should I chuck it out?
