Bak Kut Teh (Pork Bone Tea)

The combination of blanching the pork in cold water and then building the broth separately ensures clarity. Starting the pork in cold water, as Harold McGee explains in On Food and Cooking, allows soluble proteins to escape and coagulate slowly into large aggregates that are easy to skim. A hot-water start produces tiny protein particles that remain suspended and cloud the stock.

The herb bundle works on two timescales. The warming spices (star anise, cinnamon, cloves, fennel, pepper) release their volatile aromatic compounds relatively quickly, perfuming the broth within the first 30 minutes. The tougher medicinal roots (dong gui, dang shen, shu di, chuan xiong) need prolonged simmering to yield their flavor, which is why the broth tastes noticeably different at one hour compared to two. Keeping everything in a muslin bag prevents small herb fragments from muddying the soup and makes removal clean.

Toasting the garlic cloves in their skins before adding water is a technique common to Klang-style bak kut teh shops. The dry heat triggers Maillard browning on the skin and the outer layers of the clove, developing a mellow sweetness that raw garlic would not provide. The skins also act as a slow-release membrane, preventing the garlic from disintegrating into the broth too early.

The long simmer transforms collagen in the pork ribs into gelatin, which dissolves into the broth and gives it a full, lip-coating body that water alone could never achieve. This is the same principle at work in Pho Bo and Seolleongtang, where hours of bone simmering produce broths of extraordinary richness.

Herbal sachet: If sourcing individual herbs is difficult, pre-packed bak kut teh herb sachets are available at most Asian grocery stores. They are convenient but the balance of herbs varies between brands. The A1 brand from Malaysia is widely available and reasonably good. Supplement with extra garlic and white pepper to compensate for what the sachet may lack.

Pork cuts: You can use pork ribs alone and omit the belly for a leaner broth. Some versions include pork stomach, intestines, or kidney for a more traditional hawker-style bowl, though these require separate cleaning and blanching. Boneless pork shoulder can substitute for belly.

Chicken version (chi kut teh): Replace the pork with a whole chicken, cut into pieces, or with bone-in chicken thighs. Reduce the simmering time to about 45 minutes to 1 hour. The broth will be lighter and less gelatinous but still fragrant and warming.

Teochew style: For the peppery Singaporean version, omit most of the medicinal herbs (keep only a small piece of dong gui if desired) and increase the white peppercorns to 2 tablespoons, lightly crushed. Use 3 to 4 whole bulbs of garlic. Omit the dark soy sauce for a pale, clear broth. Season with light soy sauce and salt only.

Slow cooker: After blanching the pork and toasting the garlic on the stove, transfer everything to a slow cooker. Cook on low for 6 to 8 hours or on high for 3 to 4 hours. The long, gentle heat suits this dish well.

Vegetables: Daikon radish, cut into thick rounds, is sometimes added during the last 45 minutes of cooking. Leafy greens like lettuce, bok choy, or yu choy should be blanched separately and added at serving time.

Bak kut teh is traditionally a one-pot meal. A bowl of steamed jasmine rice is essential. Ladle the broth over the rice so the grains absorb the herbal, peppery liquid. Youtiao, the golden Chinese crullers, are torn into pieces and dipped into the hot soup, where they soak up the broth and become soft and savory. A small plate of thinly sliced red chilies steeped in light soy sauce provides a sharp, salty bite between spoonfuls.

For a fuller table, serve bak kut teh alongside Nasi Lemak for a spread that represents two pillars of Malaysian cooking. Chicken Rendang brings a dry, coconut-rich contrast to the soupy bak kut teh. If you enjoy pairing bone broths from different traditions, set out bak kut teh next to a bowl of Sup Kambing, the aromatic Malaysian lamb soup, for a warming double feature.

Blanched greens, particularly yu choy sum or lettuce, provide a clean, green counterpoint to the rich meat and broth. Chinese tea, particularly oolong or pu-erh, is the traditional drink pairing and helps cut through the richness.

Refrigerator: Store the broth and meat separately from the tofu puffs and vegetables, which become waterlogged if left soaking. The broth with pork keeps in a sealed container for up to 3 days. Many cooks find that bak kut teh tastes even better the next day, after the herbs have had time to release the last of their flavor into the cooled broth.

Freezer: The broth and pork freeze well for up to 1 month. Strain out the herb bag before freezing. Portion into containers, leaving headspace for expansion. Thaw overnight in the refrigerator.

Reheating: Bring the broth and pork back to a gentle simmer on the stove. Add fresh tofu puffs and vegetables at this point. Do not microwave the entire pot, as the pork can toughen. If the broth has thickened from the gelatin setting in the refrigerator, that is a good sign. It will liquefy again as it warms.

Refreshing the broth: If you plan to eat the bak kut teh over two or three days, you can add fresh water and a splash of soy sauce to the pot each time you reheat. Some Klang restaurants keep their pots going continuously, topping up the broth and adding fresh meat as needed. The flavor deepens with each cycle.
