Cachupa: Cape Verde's National Stew and Its Starchy Stain
Cachupa is the national dish of Cape Verde (Cabo Verde), the West African island nation with deep Portuguese culinary influence. It is a thick, slow-cooked stew built around hominy corn (whole dried maize kernels that have been nixtamalised or softened by soaking) and legumes (kidney beans, butter beans, or chickpeas), cooked with a variety of meats — typically linguiça (Portuguese pork sausage with paprika and garlic), chouriço, smoked or fresh pork, bacon, and sometimes salted tuna or other fish — along with vegetables (sweet potato, cassava, cabbage, plantain) and lard or vegetable oil. The two main forms are cachupa pobre ("poor cachupa," simpler, with minimal meat and primarily corn and beans) and cachupa rica ("rich cachupa," with the full range of meats and vegetables). Cachupa is typically slow-cooked for several hours until the corn kernels split and soften and the stew becomes very thick and dense. When cachupa spills on carpet, the high solid content — predominantly whole corn and bean starch — creates one of the more substantial starch-based food stains: each corn kernel or bean contains a large mass of gelatinised starch that sits in pile and must be mechanically removed before wet treatment, while the sausage fat, smoked meat components, and vegetable pigments add additional complexity.
Hominy Corn and Bean Starch: The High-Density Starch Stain
Hominy corn in cachupa is cooked until the kernels partially split and absorb the cooking liquid, each kernel holding a substantial mass of gelatinised starch. Unlike soups or stews where the starch is mostly dissolved into the liquid, cachupa contains intact kernel fragments and split kernels with exposed gelatinised starch. These should be physically removed from carpet pile first (spoon or butter knife, pressing sideways at the base of each kernel rather than pushing downward). Similarly, whole or partial beans contain gelatinised bean starch that should be removed mechanically before liquid treatment. After solid removal, the gelatinised starch residue in the carpet is treated with warm water (40°C) — rehydrating and dissolving the starch — followed by blotting. If the cashupa has cooled and the starch has set and dried, the warm water step is especially important (hot water can further gelatinise and set starch — keep at 40°C maximum). Bean starch (from kidney or butter beans) is treated identically to corn starch — warm water dissolves gelatinised starch from both legume and grain sources.
Linguiça Sausage Fat, Paprika, Smoked Pork, and Sweet Potato
Linguiça and chouriço used in cachupa contribute two distinct stain components: pork fat (approximately 38–45% saturated, predominantly palmitic acid) and paprika (ground dried red chilli/paprika pepper, which gives these Portuguese sausages their characteristic red-orange colour). The paprika in Portuguese sausage contains capsanthin and capsorubin (red carotenoids) — fat-soluble red pigments dissolved in the sausage fat. Treat pork sausage fat with cornflour (10 minutes, vacuum) then lipase enzyme (15 minutes); follow with hydrogen peroxide for the capsanthin/capsorubin from the paprika. Smoked pork and bacon in cachupa contribute additional saturated fat (pork back fat approximately 40% saturated) and Maillard browning from the smoking process — both addressed by the lipase enzyme step and partially by hydrogen peroxide. Sweet potato contributes beta-carotene (orange carotenoid) — also fat-soluble and addressed in the hydrogen peroxide step alongside the paprika carotenoids. The cassava and other vegetables contribute negligible pigment in the cooked state.

Cape Verdean Cachupa on Carpet: Common Questions
What is the full treatment sequence for a cachupa spill?
(1) Physically remove corn kernels, bean pieces, and meat chunks from carpet pile with a spoon — do not push them deeper. (2) Blot excess liquid from the stain area. (3) Cold water blotting for myoglobin from pork or other meat. (4) Cornflour across the stain — 10 minutes, vacuum (for sausage and pork fat). (5) Lipase enzyme — 15 minutes contact, blot (for pork, sausage, and vegetable oil fat). (6) Warm water (40°C) rinse and blot for gelatinised corn and bean starch residue. (7) 3% hydrogen peroxide — 10–15 minutes contact, blot (for paprika capsanthin, sweet potato beta-carotene, and Maillard browning from smoked meat). (8) Cold water rinse and blot dry. Fan-dry the area fully.
The cachupa has been sitting on the carpet overnight and the starch has dried hard. How do I treat it?
Dried and set cachupa starch on carpet requires rehydration before it can be removed. Apply warm water (40°C — not boiling, which sets starch further) directly to the dried stain and allow it to soak for 3–5 minutes; the starch absorbs water and softens from its hard, dried state back to a gelatinised consistency. Then blot (do not rub — rubbing drives softened starch deeper into pile). Repeat the warm water application and blotting 2–3 times to remove the starch in stages. Once the starch is mostly removed, proceed with cornflour (for the dried fat from sausage, which also resoftens with warm water), then lipase enzyme, then hydrogen peroxide for pigments. Dried cachupa starch is more time-consuming to remove than fresh cachupa starch but is not permanently set — it always rehydrates and can be removed with patience.
Is cachupa similar to the Brazilian feijoada or Puerto Rican sancocho in terms of stain treatment?
Cachupa, feijoada (Brazilian black bean stew with various pork cuts and sausages), and sancocho (Puerto Rican root vegetable and meat stew) all belong to the same family of Iberian-influenced slow-cooked meat-and-starch stews. The stain treatment principles are the same for all three: (1) remove solids first; (2) cold water for myoglobin; (3) cornflour + lipase enzyme for pork and sausage fat; (4) warm water for starch residue; (5) hydrogen peroxide for sausage paprika and vegetable carotenoids. The differences are in emphasis: feijoada is black-bean-dominant (more bean starch, less corn starch) and may have a stronger myoglobin stain from pork offal; sancocho uses root vegetables like yam and plantain without corn kernel starch; cachupa is the most corn-starch-heavy of the three due to the whole hominy corn kernels. For any of these stews, the solid removal step is critical first.
What makes hominy corn starch different from plain cooked rice starch on carpet?
Plain boiled rice is cooked in water, and the starch absorbs water and gelatinises — each rice grain is a water-surrounded starch matrix that is relatively water-accessible. Warm water dissolves and lifts plain rice starch effectively without a prior fat step. Hominy corn kernels in cachupa are cooked in a liquid that also contains dissolved fat (from sausage and pork fat), meaning the corn starch is partially coated in fat from the cooking liquid. This fat coating creates a hydrophobic barrier that reduces warm water penetration into the corn starch — similar to the riz gras oil-on-rice effect. The fat step (cornflour + lipase) must come before the warm water starch step in cachupa to ensure the fat coating is removed and the warm water can access the starch. Plain boiled rice does not need the fat step first; cachupa corn starch does.
