Portugal without cod would be unthinkable. Inextricably linked to Portugal's history of exploration and expansion, it was both a reason for crossing the oceans and the precious food commodity that allowed them to sail so far and wide. So they treat this beloved fish well, taking care with all its preparations. This is flavored simply with garlic and onion so as not to overwhelm its delicate flavor. Eat as-is, or heat and serve with sliced boiled potatoes and olives, all drizzled with olive oil, for a hearty Portuguese-style potato salad.
