I'm making the yule log for dessert and thought I had everything. Have already started and just found out it wasn't another tin of cocoa powder in the cupboard but bisto. I have half the amount needed and cadbury drinking chocolate, does anyone know if that will work okay? Have no way of getting to shops and have already made part so can't just wait until DP can pick some up later. Think it will be okay or should I give up and try and rush it tomorrow? Thanks
