The challenge of this month is the cod fish, a typical recipe of Livorno, a beautiful town in Italy. The two requied ingredients were cod fish and tomato, so I decided to assemble them for a very fresh mousse to soften the strong taste of cod fish boiling it in milk and mixing then to ricotta cheese, with the addition of typical little tomatoes called "datterino", similar in the shape to a light bulb. So these are the result: fresh appetizers fit also for the forthcoming Christmas holidays.
