I gave dd jacket tattie with tuna/mayo/cheese and she loved it. I went to put the jar of mayo away and its says it should be stored in the fridge (i had in the cupboard) and it said to keep for 3mth (i'm sure we have had it longer than that) now i'm worried incase she gets a tummy upset, dh seemed to think it would be ok but i'm going to worry for the rest of the day now
