Marcel Proust immortalized the madeleine in literature, yet the French never renamed the delicate cake in his honor. There are no “prousteleines” or madeleines à la Proust. By contrast, one of Portugal’s most iconic dishes bears the name of a minor 19th-century poet and noted gourmet: clams à Bulhão Pato.

The preparation is simple. Heat olive oil with garlic in a pot that can hold all the clams in a single layer, add the clams, and once they open, finish with a generous handful of chopped coriander and a squeeze of fresh lemon juice.

The dish celebrates the flavor of Portuguese clams—use anything less, and the result will fall short. Order clams à Bulhão Pato at a seaside restaurant, and you’ll understand why they are culinary poetry.
