I am informed by my European correspondent (and frequent proof-reader)that it is spelled as in the title of this post. I had it for the first time in London, in an Italian restaurant around the corner from Victoria Station,16 years ago. My European correspondent testifies that she is burnt out on it, having eaten too much of it in the years that shes has lived over there. It is easy to find here, but it is too rich for frequent indulging. But the Greek bakery's version was delicious and that will do for me for another 16 years.
