“The best fish is the freshest,” every fisherman will tell you, and by “fresh,” they mean it has been out of the water for no more than a day, often less. A large number of the inhabitants of the islands are professional or amateur fishermen: There are more boats in Greece than there are cars. And just as the fruits and vegetables in this land of blazing sun and scarce rains are small but intensely flavorful, so the fish of the Aegean are neither large nor plentiful but exceptionally delicious. Freshness definitely plays an important role in the incredible taste of even the most simply prepared fish, as anyone who has tasted the grilled fish of the island tavernas can testify.
