Humba: The Visayan Dark Braised Pork Belly With Black Beans
Humba is a Visayan (central Philippines) dish — pork belly braised in a soy-vinegar-sugar sauce with garlic, fermented black beans (tausi), banana blossoms (puso ng saging, optional), bay leaves, and peppercorns. It is closely related to adobo and paksiw na pata, but humba is distinguished by its addition of tausi (whole or mashed fermented black beans) and its Visayan origins in provinces like Cebu, Bohol, and Leyte.
On carpet, humba creates one of the darkest stains in Filipino cooking. The combination of dark soy, caramelised sugar (browning at high temperatures creates melanoidins), and the dark pigment from tausi produces a near-black or very dark brown sauce. Pork belly (a cut that is typically 35 to 45% fat by weight) releases an enormous quantity of fat into the braising liquid during cooking. Collagen from the pork belly skin and connective tissue converts to gelatin during the long braise, giving the sauce a thick, coating quality.
Component 1: Soy-Sugar Melanoidin Dark Pigment
The primary colour compound in humba sauce is melanoidin — a complex dark brown polymer formed by the Maillard reaction between amino acids and reducing sugars in the soy sauce during the long, hot braise. Soy sauce itself already contains melanoidins from its fermentation process; additional Maillard browning occurs in the pan during humba's cooking. The sugar (muscovado or white sugar) added to humba caramelises and contributes caramel polymers (caramelans, caramelens) to the dark colour.
Melanoidin and caramel polymers are water-soluble but very strongly coloured. On light carpet, humba sauce immediately deposits an intense dark brown stain. These compounds are not addressed by fat-removal or enzyme steps — the hydrogen peroxide step is the primary treatment for melanoidin pigment. Multiple rounds are standard. The vinegar in the braising liquid slightly assists the peroxide step by lowering the pH at the stain site, making the oxidation more effective.
Component 2: Tausi (Fermented Black Bean) Pigment and Aroma
Tausi (Chinese-origin fermented black beans, also called doubanjiang in simplified form) are small, soft, intensely salty and pungent black beans. Their dark colour comes from melanoidins produced during the long fermentation and drying process, plus the anthocyanins in the black soybean skin. Tausi fermentation also produces volatile amines (including TMA) and fermentation esters that contribute the characteristic pungent, salty aroma.
Tausi mashed into the humba sauce adds additional dark melanoidin pigment on top of the soy sauce melanoidin. The tausi aroma on carpet is persistent — similar in character to fish sauce but with a different fermented soybean profile. Two overnight baking soda applications are recommended for humba with a significant tausi component.
Component 3: Pork Belly Fat — Extremely High Load
Pork belly (liempo) is the highest-fat cut used in Filipino braised dishes — streaky pork belly with the skin on is typically 35 to 45% fat by weight, and much of this fat renders out into the braising sauce during the long simmer. The humba sauce, collected on carpet, carries an enormous fat load alongside the dark melanoidin pigment.
This high fat load means the standard single baking soda round used for most Filipino dishes is insufficient. Apply two full baking soda rounds before proceeding to dish soap. Do not attempt the hydrogen peroxide step until the fat is substantially removed — the fat film over the carpet pile will prevent the peroxide from contacting the melanoidin pigment layer.
Two baking soda rounds — fat removal before peroxide
Humba sauce carries extremely high pork belly fat. Applying hydrogen peroxide before removing the fat creates a barrier effect where the peroxide oxidises the fat rather than the melanoidin pigment below. Complete two full baking soda rounds and two dish soap emulsification rounds before the peroxide step.
Component 4: Pork Belly Collagen Gelatin
Pork belly skin and connective tissue (including the subcutaneous collagen layer and the inter-muscular connective tissue) convert to gelatin during the long humba braise. The humba sauce at the end of cooking is thick and coats the pork pieces with a gelatinous glaze. On carpet, this gelatin-rich sauce sets as the spill cools — act quickly, before the sauce solidifies into a thick gelatin film over the carpet pile. The protease enzyme step (20 minutes) dissolves the set pork gelatin and protein layer.
Step-by-Step Treatment Sequence
- Act immediately — humba sauce gelatin sets quickly on cooling. Remove pork belly pieces, tausi beans, and banana blossom (if present) with a spoon.
- Blot sauce — inward from edges. Do not rub the dark melanoidin into the pile.
- Cornflour or baking soda dry application (15 minutes) — to absorb the very high pork belly fat. Vacuum. Repeat (second baking soda round) — this is a high-fat dish.
- Dish soap emulsification (cold water), round 1 — for pork belly fat. Blot thoroughly.
- Dish soap, round 2 — for remaining fat and tausi residue. Rinse and blot.
- Enzyme treatment (protease + amylase, 20–25 minutes) — protease for pork gelatin and protein; amylase for banana blossom starch (if present). Blot and rinse.
- Hydrogen peroxide (3%), round 1 — for soy-sugar melanoidin, caramel, and tausi pigment. 15–20 minutes, blot, dry fully.
- Hydrogen peroxide (3%), round 2 — standard for dark soy-sugar dishes. Blot and dry.
- Hydrogen peroxide (3%), round 3 — assess before applying; use if visible dark pigment remains on light carpet.
- Baking soda overnight (first application) — for tausi fermented soybean aroma and pork belly fat residue.
- Baking soda overnight (second application) — for persistent tausi and fermented aroma compounds.
Humba vs Paksiw na Pata vs Adobo on Carpet
All three are Filipino pork soy-vinegar dishes, but they differ on carpet: adobo uses chicken or pork without the skin-on high fat of pork belly, making it a lighter fat load. Paksiw na pata uses pork knuckle — extreme collagen gelatin, moderate fat. Humba uses pork belly — extreme fat, high collagen gelatin, plus tausi dark pigment. Humba is the most challenging of the three: more fat rounds, more peroxide rounds, and more baking soda rounds for the tausi aroma.

Frequently asked
The humba was made with pork hocks (pata) instead of pork belly — some Visayan households use pata in their humba for more gelatin. Does pork hock humba create a different stain profile from pork belly humba?
Pork hock (pata) humba versus pork belly (liempo) humba on carpet: (1) Less fat, more gelatin — pork hock is significantly leaner than pork belly. Pata humba sauce has a lower fat load but an extremely high gelatin content from the knuckle joint cartilage and connective tissue. The fat treatment is reduced (one baking soda round may suffice for pata humba), but the enzyme treatment (protease) and urgency before gelatin setting are both increased. (2) Same dark sauce — the soy-sugar-tausi melanoidin pigment component is identical. Two to three hydrogen peroxide rounds are still standard for the dark sauce. (3) Gelatinous sauce coating — pata humba sauce can set into a firm, thick gelatin layer on carpet as it cools. Act within 3 to 5 minutes of the spill for pata humba — the higher gelatin content sets faster and firmer than pork belly humba. Protease enzyme with 25 minutes dwell at room temperature is the treatment for set pata gelatin. (4) Same tausi aroma treatment — two overnight baking soda applications for the tausi fermented soybean odour, unchanged from pork belly humba.
The humba included banana blossom (puso ng saging) cut into strips and cooked in the braising liquid. Banana blossom absorbs the sauce heavily during cooking and becomes dark-stained itself. Do banana blossom pieces create a specific stain concern?
Banana blossom (puso ng saging) in humba on carpet: (1) Sauce-saturated blossom pieces — banana blossom is a very absorbent ingredient. After cooking in humba sauce, the blossom strips are completely saturated with the dark soy-sugar-tausi sauce. When a blossom piece contacts carpet, it acts as a concentrated sauce delivery vehicle — releasing a large volume of dark sauce from the piece into the carpet pile on contact. Collect banana blossom pieces immediately and do not press or roll them. (2) Banana blossom starch — raw banana blossom contains starch from the young florets. After cooking in the braise, the starch is mostly gelatinised. Some starch residue remains in the pile after the blossom is removed. The amylase enzyme step addresses residual banana blossom starch. (3) Banana blossom tannins — raw banana blossom contains tannin compounds that give it an astringent, slightly bitter flavour. These tannins (primarily leucoanthocyanins and catechins) can create a brownish-grey tinge on carpet fibres if the blossom is pressed. The hydrogen peroxide step addresses tannin compounds. (4) The sauce components — the dark melanoidin and tausi pigment from the sauce absorbed by the blossom are the dominant colour challenge, not the blossom itself.
The humba was the version using muscovado sugar rather than regular white sugar. Muscovado has a strong molasses flavour and a dark brown colour. Does muscovado sugar in humba create a darker stain than white sugar humba?
Muscovado sugar versus white sugar in humba on carpet: (1) Darker sauce — muscovado sugar (also called raw cane sugar or Barbados sugar) retains the molasses syrup coating from the sugar cane, giving it an intense brown colour and a strong treacle-like flavour. Humba made with muscovado has a noticeably darker sauce than white sugar humba — the molasses polymers (similar to melanoidins) add additional dark brown colour on top of the soy and tausi melanoidins. (2) Additional molasses compounds — molasses contains humins (dark colour polymers), caramelans from the cane sugar processing, and small quantities of iron and other minerals. These compounds all contribute to the darkness of the muscovado humba sauce stain. (3) More peroxide rounds likely — muscovado humba may require three full peroxide rounds on light carpet rather than the standard two. Assess after the second round — if dark brown remains, proceed with a third round. (4) Same fat and gelatin treatment — the pork belly fat and collagen content is unchanged by the sugar type. Two baking soda rounds and the protease enzyme step are unchanged. (5) Stronger aroma from the molasses — muscovado has a richer, more complex sugar-burnt aroma than caramelised white sugar. Two overnight baking soda applications are recommended.
The humba sauce reduced completely during cooking — the pork belly was braised until the sauce had nearly evaporated and the pieces are coated in a thick, sticky glaze. This concentrated glaze is intensely dark and very adhesive. Does a dry-style humba glaze create a more severe carpet stain?
Dry-style concentrated humba glaze versus sauce-style humba on carpet: (1) More concentrated pigment per area — a fully-reduced humba glaze has a much higher concentration of melanoidin and tausi pigment per gram compared to a sauce-style humba. A pork belly piece coated in this glaze deposits a very concentrated dark pigment layer on the carpet at the contact zone. (2) Extremely sticky — the concentrated sugar caramel and gelatin in the reduced glaze make it highly adhesive. The glaze adheres strongly to carpet fibres and to surrounding pile. Do not attempt to lift the piece by pulling — slide a knife or spoon underneath to lift, minimising carpet contact. (3) Harder to treat — the concentrated melanoidin in a glaze form is more resistant to peroxide treatment than a diluted sauce. Three peroxide rounds should be planned from the start for a glaze contact. Consider a 25-minute dwell on each peroxide round rather than 15 minutes. (4) Fat treatment unchanged — the pork belly fat is the same regardless of whether the sauce is reduced. Two baking soda rounds are still required. (5) Immediate action even more critical — as the glaze has very little water, it sets even faster on carpet than a sauce. Act within 2 minutes.
