this is a tradition in many or most Italian homes. it is a basic recipe that in our home needs 4 tins of good anchovies from usually Italy. Fish cooked in frying pan with some EVO and often capers, dried black olives, hot seeds of some nature and others also use Italian bread crumbs. When finished it is gently turned into usually a thin pasta. Use some of the pasta water and the dish is complete.
now I am positive for every Italian household it is done a little differently, but the basic ingredients remain the same. and I know it sounds disgusting to many of you non Italians but when you are raised on it, you learn to love it. Very salty, but very tasty.
