Pastéis de nata, everywhere
Custard tarts are a religion. Every bakery makes them. Belém is famous (Pastéis de Belém has a permanent queue), but your neighborhood pastelaria's version might be just as good. Eat them warm.
Tip: Sprinkle cinnamon and powdered sugar on top. Order with a bica (espresso). This is the Portuguese breakfast ritual.
Bacalhau 365 ways
Dried salt cod is the national ingredient. The Portuguese say there's a recipe for every day of the year. Bacalhau à Brás (scrambled with eggs, potatoes, olives) is the most beloved.
Lunch is the big meal
Prato do dia (dish of the day) at a local tasca costs €7–10 and includes soup, main, drink, and coffee. This is how Portugal eats — simple, generous, and affordable.
