What is a 'parmigiano pearl'? I've read the following dish description in a wedding buffet menu:


  Truffle essence potato soup with parmigiano pearl


I can't seem to find any relevant results using Google Search.
This is a translation from the Italian of perle di parmigiano.  It is a mixture of egg whites and grated parmigiano formed into balls ("pearls") and deep or shallow fried.  Youtube recipes (in Italian) are shallow fried here and deep fried here.
