ok, the fruits, or rather fruit, of my labour today comprises one large meringue, in a shallow baking tray. I know for a fact that if I try to move it it will collapse (and I haven't got anything other than said baking tray in/on which to put it anyway)- it's too big for the four of us, so needs saving til Christmas, it's also too big to go in anything airtight. any bright ideas? I think my mum freezes meringue but not usually uncovered on baking trays....
