Guinea-Bissau's groundnut stew: meat or fish simmered in a thick peanut (mancarra) sauce with tomato, onion, and chili, served over the rice that is the heart of Bissau-Guinean eating. The Lusophone-Creole cousin of the mafe/groundnut-stew family.
The groundnut is one of the deepest African food survivals on Black American soil — the goober that became boiled peanuts and peanut stews of the South. Caldo de mancarra is Guinea-Bissau's groundnut pot, the Lusophone branch of the same tree.
The peanut is the nourishment and the caution at once. Groundnuts bring plant protein, heart-protective monounsaturated fat, magnesium (a key blood-pressure and insulin nutrient depleted by chronic stress), niacin, and vitamin E — a genuinely heart-friendly profile when the portion is moderate. The risk is that peanut sauce is calorie-dense and the dish is often oil-rich, so the rehabilitated version leans on a measured peanut amount, lean protein, and a controlled rice portion. Bissau-Guinean rice is often the local red/parboiled type, which is friendlier to blood sugar than polished white rice.
Brown meat or fish, build a base of onion, tomato, and chili, stir in peanut butter or fresh ground peanut paste thinned with broth, and simmer until thick and the oil rises. Serve over rice. Some versions add greens or squash.
