When I recently did a catering for a christening, one of the guests had some kind of epiphany... and it was these crostini that brought it all about. These canapés were the fourth or fifth in a succession of fingerfood and while I was assembling food in the kitchen, my daughter was bringing out the plates of food and serving them to the guests.
She usually very diligently explains what she offers people, so that there are no nasty surprises, but when she went out with these crostini, one gentleman must have been too engaged in a conversation to hear her explanations. So he grabbed one, confidently as he had liked all the things he'd had so far, ate it and when she had done the round, he grabbed my daughter by the arm and said "that was lovely, but what was it?". When she explained, he couldn't believe he had just had two mouthfuls of mushrooms, which he normally hates... and said if they always tasted like this, mushrooms would be his favourite food! So these crostini had done some magic - and in their combination with thyme, mascarpone and parmesan converted a mushroom loather into a mushroom aficionado!!!
