ok, well thats it really!!
I went onto a paul bradford sugarcraft demo last week, and he said ALL his cakes were oil based instead of conventional butter based, as this makes them slightly firmer to ice etc!
He let us taste one, and it was divine and so moist.
So i am looking for some, and i can't find any in metric, well i have found one, but that's it, and was looking for more?
