A ball of glutinous rice flour dough is wrapped around a cube of hard palm sugar, dropped into boiling water and cooked until it bobs to the surface, then rolled while wet in fresh grated coconut mixed with a pinch of salt. Bite into one and the sugar, which melted during boiling, runs out as warm caramel syrup. The dough itself is barely sweet — soft, springy, faintly chewy — so the contrast between the neutral casing, the salty coconut and the sudden burst of palm caramel is the entire pleasure of the sweet. They are sold on market trays in pale green and white, take about half an hour, and are best eaten the day they are made.","Palm sugar is the reason this sweet exists. Sugar palms grow all over the Cambodian countryside and are so tied to the landscape that the tree is a national symbol; climbers go up the trunks twice a day with bamboo ladders to collect sap from the cut flower stems, and the sap is boiled down to a thick paste that sets hard in moulds. That hard palm sugar — caramelly, slightly smoky, less sweet than cane sugar — is what goes inside num plae ai. Nothing else melts quite the same way or tastes like that.\n\nThe format is not unique to Cambodia. Similar filled glutinous rice balls appear across Asia, from Vietnamese bánh trôi to Chinese tang yuan to the Japanese and Korean varieties, and versions turn up wherever glutinous rice flour and a hard filling meet boiling water. What is Khmer is the palm sugar, the fresh coconut coating rather than a syrup bath, and the pale green colour that comes from pandan leaf juice worked into some of the dough.\n\nHome cooks make num plae ai for New Year and for Buddhist merit-making ceremonies, and they are sold year-round on street trays. The technical bit is the seal: any gap in the dough and the sugar escapes into the pot, leaving you with a plain dumpling and a caramel-flavoured saucepan. Cambodians roll the dough thin, pinch it around the sugar cube, then work the seam closed between the palms until the ball is completely smooth with no seam visible. If you can see a line, it will leak. Everything else is easy — the dough needs no rising, no proving and no skill beyond rolling.",[15,16,17,18],"Dough hydration set so it seals reliably around the sugar instead of splitting in the pot.","A sealing technique explained properly, which is the only place this sweet actually goes wrong.","Salted fresh coconut coating, so the dumplings taste balanced rather than sugary.","Optional pandan colouring using real leaves, with a note on what the powder gets you instead.",[20,21,22,23,24,25],"Add the water to the flour gradually. The dough should feel like soft modelling clay — tacky but not sticky, and smooth when rolled between the palms.","Cut the palm sugar into small cubes no larger than 1 cm. Bigger pieces stretch the dough thin and burst through as they melt.","Seal each ball by pinching the seam shut and then rolling it firmly between your palms until no line is visible at all. A visible seam always leaks.","Keep the water at a steady rolling boil. A lazy simmer leaves the dough gummy in the centre and gives the sugar time to eat through the wall.","Give the balls another minute or two after they float. Floating means the outside is cooked; the centre needs a little longer.","Roll them in coconut while still wet from the pot — dry dumplings shed the coating immediately.",[27,31,35,39],{"original":28,"swap":29,"note":30},"Hard palm sugar","Jaggery, or soft palm sugar chilled and cut into cubes","Jaggery is the closest widely available substitute.

Refrigeration ruins them: the starch retrogrades and they turn hard and chalky overnight. If you must keep them, leave them covered at room temperature and revive them by steaming for 3 minutes, which softens the dough and remelts the sugar. Uncooked dough balls can be frozen on a tray, bagged once solid, and boiled straight from frozen with 2 minutes added.",[57,60,63,66,69],{"question":58,"answer":59},"Why did the sugar leak out of my dumplings?","The seal failed. Either the dough was rolled too thin over the sugar, the seam was pinched but not smoothed, or the sugar cubes were too large and stretched the wall as they melted. Roll each ball firmly between your palms after sealing until the surface is completely smooth with no visible line, and keep the cubes under 1 cm.",{"question":61,"answer":62},"What kind of palm sugar do I need?","You need the hard, solid kind that comes as discs, cylinders or blocks and has to be chopped with a knife, not the soft spreadable paste. It has to hold its shape while you wrap the dough around it and only melt once it is in the boiling water. Jaggery works the same way. Chill soft palm sugar for an hour if that is all you can find, and cut it quickly.",{"question":64,"answer":65},"Can I make these ahead for a party?","Shape them ahead but boil them at the last minute. Uncooked balls sit happily on a floured tray for a few hours at room temperature, or freeze on a tray and go into the pot straight from frozen with an extra couple of minutes. Boiled dumplings start hardening within a few hours and are noticeably worse the next day.",{"question":67,"answer":68},"Can I use desiccated coconut for the coating?","You can, but rehydrate it first: mix it with a tablespoon of hot water and a pinch of salt and let it sit ten minutes. Dry desiccated coconut is papery and sucks moisture out of the dumpling surface. Frozen grated coconut, sold in most Asian grocers, is much closer to fresh and thaws in minutes.",{"question":70,"answer":71},"Are these dumplings gluten-free?","Yes. Glutinous rice flour is made from sticky rice and contains no wheat at all, despite the name — glutinous refers to the sticky texture, not to gluten.
