Pitche-patche, written piche-pache in Kriol, is oyster canja: a light, brothy soup of oysters and rice. Guinea-Bissau's coast is a maze of mangrove creeks and estuaries, and oysters, with crab and shrimp, are among the foods it gives.
The soup is built on peanut oil, onion, garlic and tomato. A little rice is soaked and then crushed before it goes in, so the grains break up and give the broth a gentle body, the way rice thickens a Portuguese canja. The oysters go in at the end with their own strained liquor, which carries the taste of the sea into the pot, and a squeeze of lemon and a little piri-piri finish it.
Slow Food's guide to Bissau-Guinean traditional food, made with the Bissau chef Abdon Manga, names pitche-patche de ostras, oysters with rice, tomato and lemon, among the country's representative dishes, alongside sigá and caldo de mancarra. It makes a light starter.

Ingredients
US
Metric
Serves 4
- 1 kg (about 16 to 20) oysters in the shell, or about 250 g shucked oysters with their liquor
- 70 g (about 1/3 cup) white rice (such as carolino or another medium-grain rice)
- 100 ml (scant 1/2 cup) peanut oil
- 1 large onion, finely chopped
- 2 garlic cloves, finely chopped
- 3 medium ripe tomatoes, peeled, seeded and chopped
- 1.5 litres (about 6 cups) water
- 1 lemon, juiced
- 1 to 2 piri-piri (small hot chili), finely chopped, to taste
- 1 tsp salt, adjust to taste
Instructions
- 1Cover the rice with cold water and leave it to soak for 15 minutes. Drain it well, spread it on a clean kitchen cloth, fold the cloth over and crush the grains with a rolling pin or bottle until they are broken.
- 2Meanwhile scrub the oysters and open them over a bowl to catch their liquor. Cut the oysters out of the shells into a second bowl, and strain the liquor through a fine sieve or a cloth to remove any grit.✎ Chef’s noteShucked oysters sold in a tub come with their liquor; strain it the same way. The liquor carries most of the flavour, so save every drop.
- 3Heat the oil in a large pot over medium heat and fry the onion and garlic for about 5 minutes, until soft and golden.
- 4Add the tomatoes and cook for 5 minutes more, until they soften into a sauce. Stir in the broken rice and fry it for a minute or two.
- 5Pour in the water and the strained oyster liquor, add the salt and bring to the boil. Lower the heat and simmer for 10 to 15 minutes, until the rice is soft and the broth has thickened slightly.
- 6Slide in the oysters and poach them for 2 to 3 minutes, just until their edges curl. Take the pot off the heat at once.✎ Chef’s noteOvercooked oysters turn rubbery, so pull the pot off the moment the edges frill.
- 7Stir in the lemon juice and the piri-piri, taste for salt and serve hot.

📍
Bissau. Mancarra is the local word for groundnut, so caldo de mancarra is literally peanut broth, ladled over rice. Its palm-oil counterpart is caldo de chabeu, made from the pulp of the palm fruit with okra, tomato and fish, and that is the dish that carries the palm rather than this one.

Guinea-Bissau. The cashew figure is startling: the nut has accounted for something like two thirds of merchandise exports and, by central-bank measures, the great majority of export revenue, with more than half of farming households growing it. The apple is eaten and fermented locally rather than exported, which is the half of the crop outsiders never see.
🌍
Africa. Africa's fifty-four nations hold cuisines as different as Morocco's slow-cooked tagines and South Africa's open-fire braai, yet shared threads run through them: ancient grains like millet, sorghum, and teff; stews thickened with groundnut, okra, or palm; and fiery condiments from Tunisian harissa to Ethiopian berbere. Staple starches, fufu, injera, ugali, couscous, anchor communal meals often eaten by hand from a shared dish, where hospitality is a point of honor.
The story behind this dish is up top, worth a read while the pot works.
