In the weeks leading up to Easter, Barcelona looks like an extension of Willy Wonka’s factory-fun house: chocolate castles, houses, animals, cars, motorbikes and even cartoon characters and fútbol celebrities fashioned out of cacao populate the city’s traditional patisseries. Catalonian confectioners expect to sell some 600,000 chocolate sculptures decorated with yellow chicks, chocolate eggs and cakes studded with hard-boiled eggs and colored feathers this year. The last are known as monas, and godparents traditionally give these to their godchildren throughout Catalonia and other parts of Spain to mark the holiday.
