Cow Biscuits as we always called them as kids (malted milk if your all grow'd up)
or my lush home made shortbread
or hobnobs (which can be dipped in melted plain or milk choccie depending on taste)
or my Dalek shaped ginger biccies
but like Suzi, I'm more a savoury girl so a packet of Tuc biccies, some hummous and olives and I'm happy
tell you what, I'll do the baking on the desert island then we can all be happy - Suzi can even climb a tree to get her own coconuts
not sure about making jaffa cakes, that's an art yet to be discovered in the HRC kitchen
