Cape Verdean Jagacida: Rice and Beans with Olive Oil
Jagacida is one of the most iconic everyday dishes of Cape Verde, the island nation off the west coast of Africa that was colonised by Portugal from the 15th century. The dish reflects the deep Portuguese culinary influence: it is essentially a West African adaptation of the Portuguese arroz de feijão (rice with beans), cooked in the Cape Verdean way with local additions. The base is simple — rice, beans (typically kidney beans or black-eyed peas depending on what is available), onion (caramelised in olive oil until sweet and golden), garlic, bay leaf, and olive oil. The dish is rounded and savoury but relatively mild compared to the intensely spiced West African stews. Optional additions include chouriço or linguiça (Portuguese-style smoked pork sausage seasoned with paprika and garlic — very common in Cape Verdean cooking), or dried or salt cod (bacalhau, the Portuguese staple), or both. Jagacida is served as a main course or as a substantial side dish with grilled fish, grilled meat, or on its own. The overall appearance is a moist, slightly sticky rice mixed with soft beans and onion in a light olive-oil-glossy base — distinct from the heavy palm-oil-based West African stews that have been the focus of recent guides in this series.
Rice and Bean Starch: Double Amylase Treatment
Jagacida on carpet presents two starch sources simultaneously: the rice starch and the bean starch. Cooked rice starch is highly gelatinised and forms a sticky, cohesive mass on carpet that can be scooped up while warm but hardens into a tough, waxy film as it cools. Cooked bean starch (from inside the bean seeds) is slightly more granular and less cohesive than rice starch — the bean seeds tend to break apart when the bowl is dropped, scattering fragments across the carpet rather than forming one unified starchy mass. The physical removal approach: while warm, scoop the rice and bean mixture up with a spoon. If the jagacida has cooled and hardened: warm water cloth (45–50°C) for 3 minutes over the starch deposit before scraping gently with a blunt spatula. After physical removal, apply amylase enzyme for 15 minutes — amylase digests both the rice starch and the bean starch in the same application (both contain alpha-1,4-glucosidic bonds that amylase targets). The remaining carpet treatment depends on whether kidney beans or black-eyed peas were used and what the protein and fat sources were.
Kidney Bean Anthocyanins: Cold Water First, Then Peroxide Directly
If kidney beans are used in the jagacida, the dark reddish-purple cooking liquid from the beans will stain the carpet alongside the starchy rice-bean mixture. Kidney bean anthocyanins (specifically cyanidin glycosides and delphinidin glycosides — the pigments that give kidney beans their deep red-purple colour) are water-soluble polyphenol pigments, not fat-soluble carotenoids. This is a critical distinction for treatment: unlike palm oil beta-carotene or Scotch bonnet capsanthin (which require lipase to release them from an oil matrix before peroxide can reach them), kidney bean anthocyanins are dissolved in the aqueous cooking liquid and are directly accessible to both water and oxidising agents. The treatment sequence: (1) Immediately blot with cold water (do not use hot water — heat can set some anthocyanin-carpet fibre interactions). Cold water dilutes and removes a significant fraction of the red pigment before it bonds to carpet fibres. (2) Continue cold water blotting 2–3 times until the cloth comes away much lighter. (3) No cornflour or lipase step needed for the anthocyanin component (it is not oil-embedded). (4) Hydrogen peroxide (3%) — 15–20 minutes. Peroxide oxidises the anthocyanin chromophore (the flavylium cation that gives the red colour), breaking the conjugated ring system and rendering it colourless. One peroxide pass is typically sufficient for kidney bean anthocyanins. Note: if the jagacida also contains olive oil or chouriço fat, the cornflour and lipase steps are needed for the fat component, but the anthocyanin itself does not require them.

Cape Verdean Jagacida on Carpet: Common Questions
What is the full treatment for jagacida with kidney beans and chouriço on carpet?
(1) Scoop up rice, beans, and sausage pieces. (2) Cold water blotting — 2–3 rounds — for kidney bean anthocyanin pigment (water-soluble red colour). (3) Warm water cloth (45–50°C) over hardened rice/bean starch — 3 minutes, then scrape gently. (4) Cornflour — 8 minutes, vacuum (olive oil and chouriço pork fat). (5) Amylase enzyme — 15 minutes, blot (rice starch and bean starch). (6) Lipase enzyme — 10 minutes, blot (olive oil and chouriço fat — releasing any paprika capsanthin from the sausage). (7) Protease enzyme — 15 minutes, blot (bean protein and chouriço pork protein). (8) Hydrogen peroxide (3%) — 20 minutes, blot (kidney bean anthocyanins, paprika capsanthin from chouriço, tomato lycopene if present, onion Maillard browning). (9) Cold water rinse, blot dry. Fan-dry. Black-eyed pea version (no anthocyanins): skip cold water blotting step; otherwise identical.
The kidney bean red stain looks alarming — is it harder to remove than tomato or wine?
Kidney bean anthocyanin is actually easier to remove from carpet than many red stains because it is fully water-soluble (unlike tomato lycopene which is oil-embedded, or red wine which contains a mix of water-soluble anthocyanins, tannins, and grape colour compounds). The initial cold water blotting removes a very significant fraction of the kidney bean colour before any chemical treatment is applied — unlike palm oil-based orange stains where blotting with water does almost nothing. The remaining anthocyanin after cold water blotting is then addressed cleanly by a single hydrogen peroxide application. By comparison: tomato lycopene requires lipase first (oil-release step) before peroxide can access it; red wine tannins need peroxide for the polyphenol chromophores after water blotting removes the water-soluble fraction. Kidney bean anthocyanin needs only cold water + peroxide — a two-step process, the simplest of any "red" food stain in this series. The alarming appearance is not a reliable indicator of difficulty.
Does it matter if the olive oil is extra-virgin (green) or refined (pale yellow)?
Yes, slightly. Extra-virgin olive oil contains chlorophyll pigments (chlorophyll a and b from the olive skin) that give it its distinctive green-gold colour. Refined olive oil has had the chlorophyll removed during refining and is pale golden-yellow. On carpet: extra-virgin olive oil creates a stain with a faint green tinge in addition to the yellow-gold oil mark; refined olive oil creates only the yellow-gold oil mark. Both are treated identically: cornflour absorption followed by lipase. The green chlorophyll tinge in extra-virgin olive oil is destroyed by the peroxide step (same as any chlorophyll pigment on carpet). The lipase contact time is the same for both — olive oil viscosity and fatty acid composition are virtually identical regardless of refinement level.
What if the jagacida had salt cod (bacalhau) instead of chouriço?
Salt cod (bacalhau) is dried and salted codfish, rehydrated before cooking. It contributes to the jagacida primarily as a protein source with some residual salt. For carpet staining: (1) Fish protein from bacalhau — treated by protease (20 minutes). (2) TMA/fishy odour from the rehydrated cod — bacalhau when properly desalted and cooked has a much milder fish odour than fresh or smoked fish, because salt preservation partially denatures the TMAO precursor compounds. However, if the soaking water from the bacalhau desalting was spilled alongside the jagacida, that water contains significant salt and TMAO breakdown products that should be rinsed out thoroughly with cold water immediately. (3) No paprika capsanthin from bacalhau (unlike chouriço). (4) The treatment is simpler than the chouriço version: cold water blotting (for bean anthocyanins + any bacalhau soaking liquid), amylase (rice+bean starch), lipase (olive oil only), protease (bean protein + bacalhau protein), peroxide (anthocyanins, any tomato lycopene). White vinegar step is not typically needed for properly cooked bacalhau (the TMA is lower than in fresh or smoked fish).
