Yes I cranked out the icing sugar finally. The blackberries are covering some HUGE cheesecake cracks, but the actual cake itself is as soft and melting as I always want, unlike the cakey, floury number I feared. Sister dearest informs me that whilst it was lovely, it was slightly eggy, which is probably the result of the two extra egg whites. Needless to say, I ended up with a lot of blackberries to eat after my family scraped them off.
