Lod chong is the Thai member of the Southeast Asian cendol family: short, soft green droplets of cooked rice flour (often cut with tapioca or mung-bean flour) scented and tinted with pandan, served in chilled sweetened coconut milk over crushed or shaved ice. A thick warm batter is pressed through the holes of a perforated mold or colander straight into cold water, where each strand sets into a stubby tadpole shape. The Thai name means 'passed through a hole,' a literal description of how the droplets are formed. It is eaten as both a spoonable dessert and a slushy drink, the green worms slipping up through a wide straw. The Thai version is typically simpler and lighter than its Malaysian and Indonesian cousins, leaning on fragrant coconut milk rather than a heavy palm-sugar syrup.
Lod chong belongs to the broad Southeast Asian cendol family eaten from Thailand and Malaysia to Indonesia, Cambodia and Vietnam. In Thailand it is an old court-and-temple sweet; the earliest documented Thai recipe appears in Mae Ob Chao Ka's cookbook Tamra Kap Khao Phiset (second edition 1927), which describes a green pandan lod chong pressed through a wide wooden mold and reads its strands as a representation of the god Vishnu reclining on the cosmic ocean. A separate, very popular Bangkok variant called 'lod chong Singapore' is said to have been created roughly eighty years ago by a Chinese vendor working in front of the Singapore Theatre in Yaowarat (Chinatown), who reportedly switched from rice flour to tapioca flour for a springier chew; the name is said to come from that cinema, not from the country, and that account is widely repeated but unverified. The precise origin of lod chong itself is not securely recorded.
Spoon up a mouthful and the droplets are cold, slippery and softly chewy, breaking cleanly with a gentle springiness rather than a snap. The pandan reads first as a grassy, almost vanilla-like fragrance, then the coconut milk floods in, creamy and faintly salted so the sweetness lifts instead of cloying. Crushed ice keeps everything bracingly cold and slightly diluted, and a thread of palm-sugar caramel runs underneath, rounding out the green, fresh, milky finish.
The droplets are a set starch gel. Rice flour (sometimes cut with tapioca or mung-bean flour) is cooked with water into a thick, glossy paste: heat gelatinizes the starch granules, which swell and burst so their amylose and amylopectin chains spread into a continuous, pourable gel. While still warm and fluid, the paste is forced through a perforated mold or colander into a bath of ice water; the sudden cold halts gelatinization and lets the chains re-associate (retrograde) almost instantly, firming each strand into a stubby tadpole that holds a soft, cohesive chew. Tapioca flour, being nearly pure starch, makes the strands more translucent and springy; mung-bean flour gives a firmer, cleaner-breaking bite. The green color and aroma come from pandan (Pandanus amaryllifolius), whose signature scent is the compound 2-acetyl-1-pyrroline, the same volatile that perfumes jasmine and basmati rice. A pinch of salt in the coconut milk sharpens contrast and makes the sugar taste sweeter, while palm-sugar syrup adds caramel depth; serving everything over ice keeps the gel firm and the coconut milk thin enough to drink.
Variations
The closest cousins are Malaysian Cendol and Indonesian Es Cendol, which share the green pandan droplets, coconut milk and ice but lean hard on gula melaka (dark palm-sugar syrup) and commonly add sweetened red beans, sweet corn, or even durian, often served in a bowl rather than as a drink. A distinct sibling Thai iced dessert is Tub Tim Krob, 'rubies,' where diced water chestnuts are coated in tinted tapioca flour and boiled into crunchy red jewels in pandan coconut milk over ice, a coated crunch rather than soft droplets. Within lod chong itself, droplets made mostly from tapioca flour (the 'Singapore' style) chew springier, while mung-bean-flour droplets break firmer; common add-ins include jackfruit, sugar-palm seed (luk chid), or melon, and the syrup ranges from light pandan-scented sugar water to a fuller palm-sugar pour.

How it's made
9 steps · 40 min
- 18 min
Make pandan extract: blend a handful of pandan leaves with water, then strain through a fine sieve or cloth to collect the fragrant green juice (about 120 ml).
- 23 min
Prepare an ice bath: fill a large bowl with cold water and plenty of ice, deep enough to receive the droplets.
- 34 min
In a saucepan off the heat, whisk together the rice flour, tapioca flour, mung-bean flour, the pandan juice and the rest of the water until smooth with no lumps.
- 47 min
Cook over medium heat, stirring constantly, until the mixture thickens into a glossy, translucent, very thick paste that pulls away from the sides, about 5 to 8 minutes.
Watch outCook the paste, stirring constantly, until it's glossy, translucent and pulls from the pan sides — undercook it and the droplets won't hold their shape in the ice water.
- 510 min
Working in batches while hot, ladle the paste into a perforated lod-chong mold or a colander held over the ice bath and press it through so droplets fall into the cold water and set.
Watch outPress the hot paste through the mold straight into ice water — the sudden cold sets each droplet firm on contact, so the water must be truly icy.
- 65 min
Let the droplets firm in the ice water for a few minutes, then drain; keep chilled until serving.
- 75 min
Make the coconut sauce: gently warm the coconut milk with the salt just until combined (do not boil), then cool completely.
Watch outWarm the coconut milk only until combined, never to a boil — boiling splits it and gives a greasy, grainy sauce.
- 86 min
Make palm-sugar syrup: simmer the palm sugar with a little water until dissolved into a smooth syrup, then cool.
- 94 min
To serve, divide the green droplets among bowls or tall glasses, pour over the salted coconut milk and palm-sugar syrup to taste, and top with plenty of crushed ice.
