Lao braised pork in palm-sugar caramel and fish sauce — closer to Vietnamese thịt kho than Thai braised pork.
A Lao home-kitchen classic eaten across the country — the name literally pairs "boil" with "salty," though the braise lands salt-sweet. Because meat was a rarity in village life, this rich pot was long reserved for celebrations (weddings, New Year); it also features in the Luang Prabang royal-court recipe tradition. It belongs to a wider East- and Southeast-Asian family of sweet soy-braised pork with hard-boiled eggs — Chinese dong po, Taiwanese lu rou fan, Vietnamese thit kho braised in coconut water — of which tom khem is the Lao cousin, not a derivative.
Tamarind Tree Restaurant in Vientiane (Sokpaluang Road, opened 2012) is the modern reference for tom khem; chef Souvanthong specifies palm sugar from Champasak (jaggery-style block) over Vientiane palm sugar (softer, lighter) because the block sugar caramelises more evenly.
Dark mahogany pork chunks (belly or shoulder), glossy with reduced caramel, fork-tender. Salt-sweet front (fish sauce + palm sugar), star-anise warmth, garlic-shallot depth at the back. Hard-boiled egg often braised in same pot, yolk taking up the dark colour. Served over plain jasmine rice, not sticky.
Caramel goes first — palm sugar melted dry to deep mahogany (about 175°C) before any liquid hits the pan; pour fish sauce in too early and it crystallises into rock candy. That caramel-sugar reduction is what gives Lao tom khem its dark colour and a sweetness that stays the right side of cloying, and a deeper, less coconut-tinged tone than the Vietnamese thit kho it sits alongside.
Variations
Plain pork-belly tom khem is the most common, especially around Vientiane; the pork-with-egg version is the everyday family meal; a Luang Prabang style braises duck instead. Hmong households sometimes use buffalo and skip star anise, leaning on white pepper instead.

How it's made
4 steps · 13 min active + 1 hour waiting
- 110 min
Caramelize 80 g palm sugar in 2 tbsp oil; add 500 g cubed pork; brown.
Watch outMelt the palm sugar to a deep mahogany before the pork goes in and before any liquid — pour fish sauce in too early and it seizes into hard candy; too pale and the dish loses its dark color and depth.
- 23 min
Add 2 tbsp fish sauce + 500 ml water + 6 garlic + soft-boiled eggs.
- 350 min
Simmer covered 50 min until pork is tender.
Watch outSimmer covered until the pork cubes are fork-tender and the sauce has darkened — the color should read deep and glossy, sweet but not cloying.
- 410 min
Reduce uncovered 10 min; serve with rice.
Watch outReduce uncovered just until the sauce coats a spoon and clings to the pork — go too far and the caramel tips from rich to burnt-bitter.
