A work colleague today appeared with several take-away tubs filled with Goop and some instruction.
Apparently it's a German Friendship Cake. You feed it and stir for 10 days, split it into 5 portions. Pass 4 potions onto friends (hence Friendship) and bake the 5th.
I've been googling it and found this fab blog about it. I'm happy to try the original recipe, although my DD isn't keen on sultanas. I think I'll make make a carrot or cherry version for her.
I'm looking forward to the final cake.:o)
Quite fancy having a go at Sourdough bread too.
