Arroz de Ostras
Guinean oyster rice with tomato, peanut oil, chilli and a lemon finish.

About Arroz de Ostras
Pitche-patche de ostras is identified as arroz de ostras in the Guinea-Bissau tourism guide. Felicia Sampaio’s recipe combines oysters with broken Carolino rice in a broth flavoured by tomato, onion and garlic.
The rice is soaked and crushed before joining the sautéed aromatics. Peanut oil provides the cooking medium, while water and the oysters’ strained liquid form the broth.
Oysters cook in the simmering mixture, with salt and piripiri among the seasonings. Lemon juice is added after the pot leaves the heat, and the finished oyster rice is served hot.
