The geographical and historical influences that inform Portuguese cuisine set it apart from the food traditions of its Spanish neighbors. Staple foods from North and South America, China, Japan and Africa obtained during explorations in the 15th and 16th centuries combine with native foods to create a flavorful, interesting Portuguese diet.

The corn, tomatoes, chilies and peppers used frequently in Portuguese cuisine originated in North and South America. Baalhau, or salt cod, dries in racks in localities along the Portuguese coasts. Portugal uses rice more than other European countries, according to the Epicurious website, and couscous, a fine pasta, is a common ingredient from its Moroccan neighbors to the south.

Porco preto, or black pig, from the southern region Alentejo, is succulent and sweet, because the black pigs graze on fallen acorns. Chourico and linguica are cured smoked sausages seasoned with red pepper, garlic, herbs and wine. Morcela is blood sausage, a popular dish that may be the Portuguese answer to surf and turf -- pork and clams.

The cheese in Portugal is often made with sheep's or goat's milk. Quiejo fresco is a commonly used mild soft, creamy cheese. San Jorge is a cheese similar to cheddar from Azores, an Archipelago off the western coast. The Portuguese revere the egg; it may be their most heavily used ingredient. Fried and placed on top of meats and yolks in custards, the Portuguese use eggs in almost every course.

Arroz doce is rice pudding with cinnamon. Custards are common. Flan is a custard with caramel added. Port is perhaps the most popular Portuguese wine. It originated in Oporto, a city in the north. An estimated 40 varieties of grapes, according to Frommers, and up to 50 years of aging form the complex flavor of port. The types range from white to full-bodied reds. Often consumed after meals, ports are paired with cheese and fruit.
