Maafe: Senegal's Groundnut Stew and Its Dense Stain Profile
Maafe (also spelled mafé, tigadèguèna in Bambara, or domoda in Gambia) is one of the most iconic dishes of Senegalese and broader West African cuisine, particularly associated with Mandinka, Wolof, and Soninke cooking traditions. The dish consists of meat — traditionally lamb, but beef and chicken are also common — browned in oil, then slow-cooked in a thick sauce made from groundnut (peanut) paste, tomato paste (and often fresh tomato), onion, garlic, chilli pepper, and sometimes vegetables (sweet potato, carrot, turnip, or cassava). The groundnut paste is the defining ingredient: it thickens the sauce into a rich, opaque, light-brown to orange-brown stew with a distinctive nutty, earthy depth. Maafe is typically served over plain white rice. When maafe spills on carpet, the thick groundnut paste creates one of the denser, more substantial food stains: the peanut paste contains approximately 50% fat and 25% protein by weight, making both the fat and protein components significant and requiring both lipase and protease enzyme treatment for thorough removal.
Groundnut Paste: High-Density Fat and Legume Protein
Groundnut paste (peanut paste, similar to peanut butter but typically coarser and without added sugar or salt) used in maafe is approximately 50% fat and 25% protein. Peanut oil is approximately 18% saturated fat — lower saturation than palm fat or animal fats — meaning it remains relatively fluid at room temperature and penetrates carpet pile readily. The protein component (primarily arachin and conarachin, the major legume storage proteins in peanuts) is substantial and creates a dense protein stain alongside the fat stain. Treatment: (1) blot excess maafe from carpet surface — the thick consistency means it does not spread widely immediately; (2) apply cornflour for 10 minutes to absorb the surface fat; (3) vacuum; (4) cold water blotting (for the lamb myoglobin and to reduce protein saturation before enzyme treatment); (5) protease enzyme for 20 minutes (for the arachin/conarachin legume proteins and the lamb protein); (6) lipase enzyme for 15 minutes (for the peanut oil); (7) blot after each enzyme step; (8) hydrogen peroxide for the tomato lycopene. Both enzyme steps are essential — skipping the protease will leave a protein residue that dries to a pale brown film.
Concentrated Tomato Paste Lycopene
Maafe uses tomato paste (pâte de tomate, the double or triple-concentrated canned tomato product common in West African cooking) rather than fresh tomato or passata. Triple-concentrated tomato paste has a lycopene concentration approximately 10 times that of fresh tomato — a small spoon of tomato paste in a maafe stew contributes as much lycopene to the stain as the equivalent of several fresh tomatoes would. This concentrated lycopene creates a more vivid and persistent red component in the maafe stain than dishes using fresh tomato or dilute tomato sauce. The lycopene in maafe is dissolved in the peanut oil (lycopene is fat-soluble), and the lipase enzyme step must precede the hydrogen peroxide step — removing the fat carrier first maximises the peroxide's access to the free lycopene. Apply hydrogen peroxide after the lipase step: 10 minutes contact, blot. If a red-orange tinge remains, a second hydrogen peroxide application is recommended for tomato paste maafe.
Lamb Myoglobin and Rendered Lamb Fat
Lamb is the traditional meat for Senegalese maafe, browned in oil before slow-cooking in the groundnut sauce. Browning creates Maillard browning on the lamb surface — these complex Maillard reaction products contribute a light brown tinge to the stew. Cold water blotting immediately for lamb myoglobin (never hot water — permanent setting). The Maillard browning from the lamb surface does not respond to enzyme treatment but partially responds to hydrogen peroxide. Rendered lamb fat (approximately 50% saturated) in the stew contributes to the total fat load alongside the peanut oil — both are addressed by the lipase enzyme step. If beef is used instead of lamb, the stain profile is essentially identical.

Senegalese Maafe on Carpet: Common Questions
How is a maafe stain different from a peanut butter stain?
Maafe groundnut paste and peanut butter are chemically very similar — both are approximately 50% peanut fat and 25% peanut protein, and both are treated the same way (cornflour, protease enzyme, lipase enzyme). The key differences in the carpet stain are: (1) Dilution — maafe sauce is thinned with water/stock during cooking and contains other ingredients, so it is less dense than pure peanut butter. This means it spreads more widely per unit volume but creates a shallower stain depth than the same weight of peanut butter; (2) Tomato — maafe contains concentrated tomato paste lycopene which peanut butter does not, adding a red component that requires hydrogen peroxide treatment; (3) Lamb fat — rendered lamb fat in the sauce adds to the fat load; (4) Onion, garlic, and pepper contribute very minor pigment. The core treatment is identical: protease + lipase enzyme, then hydrogen peroxide for the tomato component.
I used cashew paste instead of groundnut paste in my maafe — does the treatment differ?
Cashew paste has a similar fat and protein profile to groundnut paste but the fat composition differs: cashew oil is approximately 20% saturated (slightly higher than peanut oil's 18%) and higher in oleic acid. The stain treatment is essentially the same — cornflour for fat absorption, protease enzyme for cashew protein (cashew proteins — mainly legumin and vicilin-like proteins — respond to protease enzyme), lipase enzyme for cashew fat. Cashew paste produces a stain very slightly lighter in colour than groundnut paste (as cashews are lighter than peanuts), but this has no practical treatment implication. The tomato lycopene treatment is unchanged.
The maafe has sweet potato in it — the orange pieces left a stain. How do I treat it?
Sweet potato contributes two stain components: beta-carotene (the orange-yellow pigment from the orange flesh of the sweet potato — the same compound as in carrots) and cooked sweet potato starch. Sweet potato beta-carotene is fat-soluble in the groundnut oil sauce and responds to hydrogen peroxide (addressed by the same peroxide step as the tomato lycopene). Sweet potato starch is gelatinised from cooking and treated with warm water after the fat and protein enzyme steps. The combined lycopene + beta-carotene stain from maafe with sweet potato may benefit from two hydrogen peroxide applications rather than one.
What is the complete treatment sequence for a typical maafe spill?
(1) Blot excess maafe from carpet — work from edges inward, no rubbing. (2) Cornflour across the full stain area — 10 minutes, vacuum. (3) Cold water blotting for lamb myoglobin. (4) Protease enzyme — 20 minutes contact, blot (for arachin/conarachin legume protein, lamb protein, Maillard products). (5) Lipase enzyme — 15 minutes contact, blot (for peanut oil and lamb fat). (6) 3% hydrogen peroxide — 10 minutes contact, blot (for tomato paste lycopene, plus any sweet potato beta-carotene and Maillard browning). (7) If red-orange tinge remains: second hydrogen peroxide application, 10 minutes. (8) Cold water rinse and blot dry. Allow carpet to dry fully — a fan directed at the stain area accelerates drying. Do not walk on the treated area until dry.
