If you decide to spend a few days in Portugal, it is important that you know a little more about its gastronomy. Let’s start with breakfast . This usually consists of a toast of bread with butter, cheese or preserved fruits accompanied by a coffee or milk. Sweet pastries, cereals or yogurt can also be eaten.
A lot of fish and shellfish are included in the Portuguese diet. Fish is served grilled, boiled (including steamed and simmered), fried, and even braised or roasted. The type of fish that is most consumed is cod . This is almost always used dry and salty since the Portuguese fishing tradition began before refrigeration was invented. Cod has to be soaked in water or sometimes in water before cooking. 
The simplest fish dishes are often flavored with virgin olive oil and white wine vinegar. Also popular are sardines (especially grilled), octopus, squid, cuttlefish, crabs, shrimp and prawns, lobster, and many crustaceans, such as barnacles.
La Caldeirada is a stew that consists of a variety of fish and shellfish with potatoes, tomato and onion. The consumption of meat and poultry has historically been a privilege of the upper classes. Meat was a staple on the table of a nobleman in the Middle Ages. During winter, a common Portuguese dish is the Portuguese stew . This is a rich stew with bones and pork and chicken. It is served with cabbage, carrots, turnips, chorizo, rice and potatoes.
