Amêijoas na cataplana is a traditional seafood dish made by cooking clams in a cataplana, a special copper or metal cooking vessel that seals in flavors. The clams are typically combined with ingredients like garlic, onions, chourico, presunto, bacon, white wine, herbs, and olive oil, creating a rich, flavorful broth.

The cataplana pot allows the dish to steam, keeping the clams tender and aromatic. It's a popular dish in coastal regions of Portugal, especially in the Algarve.
