Creamy Custard Tarts in Lisbon

The Tagus River meets the sea at Lisbon, and it was from the city’s historic riverside district,
Belém, that Portuguese explorers set sail, their discoveries creating an empire for Portugal.
The most famous of all, Vasco da Gama, set his course for India here, and his fame is perhaps matched by a pastry first produced in Belém in 1837, and now the country’s favorite treat.
