I'm like that too, @GoneWishing. I don't tend to run out of stuff because I keep stocks in generally. I now have more stocks in than usual, but I'm a 'full cupboards / freezer' person anyway.
Someone on another thread said they didn't have room for 3 days' supplies in their house, which surprised me. Surely that's just having a normal fridge, freezer and cupboard space?!
I'm confident that I could 'do Christmas' now from my stores, if necessary. Which is a comfort to me, it has to be said. I'm going to make my Christmas puddings soon (I'm doing mini ones for DH and DS) so they'll be done too. I think I'll buy my oranges for pastry and freeze the zest / juice now too. Il add to my list!
