One of the tricky things about trying to cook Italian recipes in New England is that many of the ingredients are different, especially with regard to seafood. Most of Italy is far closer to where the crops are grown than New England is to California's Central Valley, so their produce tends to be fresher all year round. But for seafood, the fish and shellfish in our waters are in most cases very different from Mediterranean waters.
This recipe calls for Maine shrimp, the delicious little cold-water shrimp from the Bay of Fundy that are not the same as "salad shrimp" that you can get at some food service outlets. Italy has shrimp of all sizes, including little shrimp like these, but I doubt that they are the same species in those warmer waters. Nevertheless, they get us closer to the way this recipe would be made in Venice or Genoa.
