You know how Christmas cake recipes all call for Apricot Jam to stick the marzipan to the cake? And how no other jam works/tastes quite the same so you're forced to buy some even though it's actually disgusting? And how the jar you bought for Christmas '11 will be mouldy by Christmas '12 so you can't even keep using the same jar?
I can solve the problem. You need to book yourself into a hotel and make sure breakfast is included. Then you nick the little pots of (apricot) jam they serve. Job's a good 'un.
Do we have any more?
