Thanks everyone.

My side of the family does not have generations of traditional christmases, and i really have no one to ask. Except Google. And google was vague and confusing (perhaps having consumed too much brandy).

Can i just say i was so blimin proud of myself for baking the cake - i don't want to ruin it. I'll put a tiny bit in. 11 weeks to go. Maybe no more than 2 mls a week.

ETA - ah, LuluHB, never thought of OJ. Hmm, that's an idea.
