Earlier this week I ate the frozen 'leftovers' from last December's Christmas lunch. (i.e. the 8 frozen 'pigs in blankets' which remained from the packet of 12 which I'd bought, together with defrosted 'fresh' stuffing and the mini-Yorkshire puddings which I'd frozen, accompanied by the frozen potato wedges I'd bought for Christmas lunch, all covered in gravy made from granules with a 'best before' date of May 2011).
I'm sill here!!!
(I'd have no worries about using frozen bacon from February of LAST year but, as Gingejbee suggests, the quality may have deteriorated over time).
