A few weeks ago I went to open a jar of pesto from the fridge. The lid didn’t pop, it came off like it had already been opened and the pesto was mouldy. I chucked it away and forgot about it. I just went to open a jar of passata today and the same thing happened, only it wasn’t mouldy.
DH swears he’s not opening jars and putting them back but it seems bizarre. Anyone else had this?!
