My first job was at Carvel in 1982 and I spent the entire summer making ice cream cakes because EVERYONE was using them for parties. I did wedding cakes, shower cakes, birthday cakes, you name it. So I was not surprised that ice cream cake was the showstopper. Never heard of finger donuts, though.
I was so disappointed that no one made the joke about how real men do eat quiche, but maybe the book didn't make it to the UK.
