Dholl Puri: Mauritius's National Street Food and Its Multi-Accompaniment Spill
Dholl puri is widely regarded as the national street food of Mauritius and is deeply embedded in Mauritian Creole and Indo-Mauritian culture. The name comes from "dholl" (split yellow peas — chana dal or matar dal) and "puri" (the flatbread, though in Mauritius the term is used loosely — the flatbread is more like a thin roti than a deep-fried puri). To make dholl puri, split yellow peas are cooked, dried, and ground into a fine powder, then kneaded into the wheat flour dough with salt and turmeric — giving the flatbread its characteristic pale yellow colour and distinctive earthy legume flavour. The dough is rolled very thin and dry-cooked on a tawa (flat iron griddle). Dholl puri is served rolled up or folded around a combination of accompaniments, typically including: rougaille (Mauritius's foundational Creole tomato sauce — crushed tomatoes cooked with garlic, ginger, fresh thyme, and scotch bonnet chilli in oil), curried haricots or lima beans (cooked in a turmeric and curry spice sauce), and achard (pickled vegetables — typically green mango or choucroute cabbage with mustard seeds and turmeric). When dholl puri is eaten at home and spills, the stain combines multiple components from the flatbread and all its accompaniments simultaneously — and turmeric curcumin from the curried beans or from the dholl puri dough itself is typically the most stubborn and last-to-clear component.
Turmeric Curcumin: The Most Stubborn Dholl Puri Stain Component
Turmeric is present in dholl puri from multiple sources: (1) in the flatbread dough itself (a pinch of turmeric gives dholl puri its pale yellow colour); (2) in the curried lima beans or haricots accompaniment, where turmeric is a primary spice; (3) in the achard pickling mixture, which often includes turmeric as a preservative and colourant. The active staining compound in turmeric is curcumin — a polyphenol (diarylheptanoid) with a distinctive bright yellow-orange colour. Curcumin is partially fat-soluble and partially water-soluble, and it is one of the most persistent natural food pigments on carpet fibres. The treatment for curcumin staining follows the general stain sequence but requires particular attention at the peroxide step: (1) Cold water blotting removes the water-soluble fraction of curcumin from the rinsing liquid; (2) Lipase enzyme after cornflour removes the fat phase in which some curcumin is dissolved (rougaille cooking oil, dholl puri dough fat); (3) First hydrogen peroxide application (20 minutes — longer than standard for curcumin) bleaches the curcumin pigment. If yellow tinge remains after the first application, allow the carpet to dry slightly, then apply a second hydrogen peroxide application (15–20 minutes). In some cases of heavy turmeric spills, three peroxide applications are needed over consecutive days. Do not apply heat (hairdryer) to a curcumin stain — heat accelerates curcumin setting in carpet fibres and makes it more resistant to peroxide. Always fan-dry naturally.
Rougaille Tomato Sauce, Split Pea Starch, and Legume Protein
Rougaille (Mauritian Creole tomato sauce) contributes tomato lycopene (red, fat-soluble — addressed by lipase then peroxide), scotch bonnet chilli capsanthin and capsorubin (orange-red carotenoids — also addressed by lipase then peroxide), and cooking oil (lipase). The combined rougaille pigments (lycopene + capsanthin) respond to the same peroxide treatment as the turmeric curcumin — but they bleach faster than curcumin and are typically clear after the first peroxide application. The dholl puri flatbread itself contributes: split yellow pea flour starch (amylase enzyme dissolves gelatinised legume starch from the cooked flatbread), wheat flour starch (also amylase), and split pea protein (protease enzyme addresses the legume protein). The curried lima beans or haricots add: lima bean protein (protease), legume starch (amylase), and curry spice oil (lipase). The achard pickled mango or vegetable juice adds: pickling liquid (acetic acid — water-soluble, removed by cold water blotting), green mango polyphenols (pale yellow, addressed by peroxide), and mustard seed oil (lipase). The combined enzyme sequence — cornflour → lipase → protease → amylase → peroxide (×2 for curcumin) — addresses all components of a typical dholl puri spill including all accompaniments.

Mauritian Dholl Puri on Carpet: Common Questions
What is the full treatment sequence for a dholl puri spill (with accompaniments) on carpet?
(1) Remove solid flatbread and bean pieces with a spoon. (2) Cold water blotting (removes water-soluble fraction of curcumin, achard pickling liquid, and water-soluble rougaille components). (3) Cornflour — 10 minutes, vacuum (for rougaille cooking oil and dholl puri dough fat). (4) Lipase enzyme — 15 minutes, blot (for rougaille oil, dough fat, and any bean curry oil — breaks down fat carrying curcumin, lycopene, and capsanthin). (5) Protease enzyme — 20 minutes, blot (for split pea protein, lima bean protein, and any meat protein if the rougaille contained meat). (6) Amylase enzyme — 15 minutes, blot (for gelatinised split pea and wheat flour starch from the flatbread and lima bean starch from the curried beans). (7) First hydrogen peroxide (3%) — 20 minutes, blot (curcumin requires longer contact than standard — 20 minutes minimum). (8) Fan-dry briefly (5 minutes), then second hydrogen peroxide — 15–20 minutes, blot (curcumin often persists through the first application on carpet). (9) Assess: if yellow tinge remains, allow to dry fully and repeat peroxide the following day. (10) Final warm water rinse (40°C), blot. (11) Cold water rinse, blot dry. Fan-dry fully.
Is the yellow stain from the dholl puri flatbread itself or from the turmeric in the accompaniments?
Both — but the accompaniments are typically the primary source of heavy turmeric staining. The dholl puri flatbread contains a relatively small amount of turmeric in the dough (enough to give the flatbread a pale yellow colour, but not a deep yellow). The curried lima beans or haricots accompaniment contains substantially more turmeric — turmeric is typically added by the tablespoon to a pot of curried beans, compared to a pinch or less in the flatbread dough. If the stain is pale yellow (from the flatbread only — e.g. the flatbread fell and the accompaniments were kept separate), one peroxide application of 15 minutes is usually sufficient. If the stain is bright or deep yellow-orange (from the curried bean accompaniment), treat for heavy curcumin with two applications of 20 minutes each. The achard also contributes a small turmeric component from the pickling mixture — in practice, when dholl puri is eaten wrapped with all its accompaniments, the stain should be treated as a heavy curcumin spill regardless of which component appears dominant.
What is "rougaille" and does it need a different treatment from standard tomato sauce?
Rougaille is Mauritius's foundational Creole tomato sauce — a cooked-down mixture of crushed tomatoes, garlic, ginger, fresh thyme, and scotch bonnet chilli, fried in oil. It differs from Italian tomato sauce in two stain-relevant ways: (1) Chilli capsanthin: rougaille uses scotch bonnet chilli rather than mild red chilli or no chilli. Scotch bonnet chilli has a high concentration of capsanthin and capsorubin (orange-red carotenoids) — these are fat-soluble and require lipase before peroxide. Italian tomato sauce typically has minimal capsanthin (no or mild chilli). The lipase step is more important for rougaille than for plain tomato sauce; (2) Fresh thyme: fresh thyme in rougaille adds a small green herbal pigment component (chlorophyll from fresh thyme leaves). This is a minor stain compared to the tomato and chilli components and is addressed by the same peroxide step. In practice, treat rougaille the same as a spicy tomato sauce: cornflour → lipase (more important here) → protease → peroxide. No special rougaille-specific step is needed.
The dholl puri spill also contains vindaye sauce — does that change the treatment?
Vindaye (Mauritian mustard and turmeric pickle sauce — typically used with fish, octopus, or other seafood) adds additional stain components when it accompanies dholl puri: (1) Mustard seed: mustard gets its yellow colour from sinalbin (in white mustard) or sinigrin-related glucosinolates — these are not the same as curcumin. Mustard yellow on carpet responds well to hydrogen peroxide (faster than curcumin) and is usually cleared in one application; (2) Additional turmeric: vindaye typically uses a significant amount of turmeric (more than rougaille) — this intensifies the curcumin component of the stain. Treat as heavy curcumin with two peroxide applications; (3) Mustard oil or vegetable oil in vindaye: lipase enzyme addresses this. If the vindaye contains fish or octopus, add a protease enzyme step extended to 25 minutes for the fish/seafood protein. Vindaye also has a pungent mustard aroma — the volatile mustard compounds (isothiocyanates) are largely water-soluble and dissipate on their own; rinse with cold water.
