Chicken inasal is a grilled chicken dish from Bacolod City, Negros Occidental — widely regarded as among the best grilled chicken in the Philippines and a source of strong regional pride. The chicken is marinated in a mixture of vinegar, calamansi, lemongrass, ginger, garlic, and often turmeric, then grilled over live charcoal while continuously basted with a mixture of annatto seeds (atsuete) infused in oil and margarine or butter. The result is a glistening orange-red chicken with a distinctive charcoal-and-annatto aroma. Inasal is widely available at Filipino restaurants and is commonly prepared at home for gatherings in Sutherland Shire's Filipino community.
The annatto oil basting is the defining carpet stain element of chicken inasal. Unlike kare-kare (where annatto seeds are briefly steeped in hot water or oil for sauce colour) or palabok (where annatto powder colours the sauce), inasal involves repeated basting of the chicken with concentrated annatto-infused oil during the full cooking time. The drip from the basting process accumulates on the serving plate and under the serving rack. When this annatto-oil drip contacts carpet — from a tipped plate, a serving rack placed on the floor, or sauce spilled during portioning — it delivers a highly concentrated bixin load to the carpet fibres.
Inasal Stain Component Analysis
| Component | Stain Element | Treatment Step | H2O2 Rounds |
|---|---|---|---|
| Annatto basting oil (concentrated) | Bixin (orange-red apocarotenoid — high density) | H2O2 | 2 |
| Margarine/butter in basting | Milk fat (saturated + butyrate) | Baking soda 16–18 min + lipase | Not applicable |
| Chicken fat (rendered during grilling) | Long-chain saturated fat | Baking soda + lipase | Not applicable |
| Turmeric (dilaw) in marinade | Curcumin (bright yellow) — if used | Baking soda alkaline — NOT vinegar | H2O2 round 2 |
| Calamansi/vinegar marinade | Citric/acetic acid (mild) | Dilute with cold water | Not applicable |
| Charcoal grill char | Carbonised compounds (minor) | H2O2 incidental | 0 |
Turmeric in Inasal: The Alkaline Rule
If the marinade contained turmeric — skip the vinegar step
Some inasal marinades include turmeric (dilaw) for additional yellow colour alongside the annatto. If the chicken had a yellow-orange tint from turmeric (not just the orange from annatto), skip the vinegar step and use an extended baking soda application instead. Vinegar makes curcumin brighter yellow and harder to remove. Both annatto bixin and turmeric curcumin respond to H2O2.
Treatment Sequence
- Remove chicken pieces from the carpet. Blot the annatto oil drip from the outside inward.
- Apply baking soda paste (1 tablespoon baking soda + 1 teaspoon cold water). Leave 16–18 minutes for the combined chicken fat and margarine/butter fat from the basting mixture.
- Rinse baking soda with cold water. Blot dry.
- Apply enzyme cleaner (lipase for chicken fat and margarine fat; protease for any chicken protein). Leave 16–18 minutes.
- Rinse with cold water. Blot dry.
- Vinegar step (no turmeric in marinade): Apply white vinegar solution (1 part vinegar, 4 parts cold water). Leave 5 minutes. Blot dry. Turmeric present: Skip vinegar — apply a fresh baking soda paste (6 minutes) instead to maintain alkaline pH.
- Apply 3% hydrogen peroxide. Leave 10 minutes. Blot. Round 1 partially fades the annatto bixin and addresses turmeric curcumin if present. Allow the carpet to fully dry.
- Apply a second H2O2 round after full drying. Leave 10 minutes. The annatto bixin from concentrated inasal basting oil consistently requires 2 H2O2 rounds on synthetic carpet. Rinse with cold water. Blot dry. Air-dry.
Inasal Annatto Oil Stain on Sutherland Shire Carpet?
Concentrated annatto bixin from inasal basting oil that persists after two H2O2 rounds typically requires professional oxidative extraction — commercial peroxide concentrations and extraction heat address bixin bonded to synthetic carpet fibres more effectively than household H2O2 alone. Local carpet cleaning specialists can be matched through referral networks serving Sutherland Shire.

Frequently asked
Is the annatto oil from inasal basting more concentrated than the annatto in kare-kare sauce?
Yes — inasal basting oil is essentially annatto seeds steeped in cooking oil, producing near-pure bixin-in-oil at relatively high concentration. Kare-kare sauce dilutes the annatto colour across a large volume of broth and peanut sauce. Palabok sauce uses annatto in a water-based sauce at a moderate concentration. Inasal basting oil is the most concentrated annatto source of the three dishes per unit volume that contacts carpet. Two H2O2 rounds are more reliably needed for inasal basting oil than for kare-kare sauce.
The inasal was served with achara (pickled green papaya) — does achara on carpet need separate treatment?
Achara (atsara — pickled green papaya with carrots, bell pepper, ginger, and vinegar) creates a mild, sweet-sour, yellowish-orange stain from the bell pepper capsanthin (minor) and carrot beta-carotene (minor). The vinegar in achara provides mild carpet acidity. Treat achara as a simple vegetable-vinegar stain: blot, cold water rinse, 1 H2O2 round. Do not let achara vinegar contact a turmeric stain from the inasal — vinegar brightens curcumin.
What if the inasal drip came from the serving tray rather than directly from the chicken?
The serving tray for chicken inasal accumulates a concentrated annatto oil drip during the cooking and serving process. This tray drip is essentially pure annatto basting oil — no dilution from the chicken's water content. A tray drip stain on carpet has the highest bixin concentration of any inasal-related spill. Treat identically (2 H2O2 rounds, baking soda for fat), but expect the residual orange to be more persistent than a sauce drip from the chicken itself.
Does the Bacolod inasal style differ stain-wise from Bisaya or other regional inasal variants?
Bacolod inasal is the most widely known and has the most codified basting practice (continuous annatto oil basting). Other regional variants may use less basting oil, lighter annatto, or different marinades. If the inasal had a bright orange-red surface colour from heavy annatto basting (classic Bacolod style): plan for 2 H2O2 rounds. If the inasal was lightly coloured (pale yellow from turmeric, less annatto basting): 1 H2O2 round may be sufficient with assessment after drying.
