Nam Prik Ong

Northern Thai roasted tomato and minced pork chilli relish: the Lanna tradition of Chiang Mai, served with sticky rice and raw vegetables

Origin: Chiang Mai, Northern Thailand (Lanna region)

From the journey of Chilli Pepper.

Nam prik ong (น้ำพริกอ่อง) is the defining relish of the Lanna culinary tradition centred on Chiang Mai, a northern Thai heritage distinct in character from the coconut milk-based curries of the south and the fish-sauce-driven salads of the northeast. The Lanna Kingdom (1292 to 1775 CE) occupied the highland valleys of what is now northern Thailand, its culture shaped by proximity to Burma, Yunnan, and the Shan states rather than by the maritime trade networks that defined the central plains. The cuisine that developed from this geography centres on sticky rice eaten by hand, fermented and dried preparations, and the category of pounded relishes and pastes known collectively as nam prik. Nam prik, literally chilli water or chilli paste, encompasses dozens of preparations across Thai regional traditions, each defined by its secondary ingredients and the character of the region that developed it. What sets nam prik ong apart from every other variety is the tomato. Roasted Roma or cherry tomatoes are pounded directly into the dried chilli and fermented shrimp paste base alongside minced pork, producing a relish that is simultaneously spiced and fruited, sharp and rich. This is the most tomato-forward preparation in the Thai kitchen: the dish in which the tomato functions not as a souring garnish or a secondary element but as a structural ingredient that provides body, roasted sweetness, and a bright acidity throughout. The pork is cooked within the paste itself, not alongside it; the fat renders into the chilli and tomato, the moisture from the roasted tomatoes evaporates as the mixture fries, and the result is a thick, aromatic paste in which meat, chilli, and tomato are inseparable. Nam prik ong is served at room temperature or warm, surrounded by raw vegetables (cucumber, white cabbage, long beans, spring onion) and sticky rice shaped into small balls by hand for dipping. Deep-fried pork rinds (kaeb moo) are the traditional accompaniment, their fat and crunch a deliberate counterpoint to the paste's bright acidity. This combination of paste, sticky rice, and raw vegetables is the central eating pattern of northern Thai daily life: communal, unfussy, and built for a table where every diner takes precisely what they want.

Ingredients

Chilli Paste

  • 10 large dried red chillies, stems and seeds removed, soaked in warm water for 10 minutes and drained
  • 4 shallots (approx 80g), peeled and halved
  • 5 cloves garlic, unpeeled
  • 1 stalk lemongrass, white part only, roughly sliced
  • 2 cm fresh galangal (or ginger), peeled and roughly sliced
  • 1 tsp kapi (Thai fermented shrimp paste), wrapped in foil and dry-roasted in a pan for 1 minute per side
  • 0.5 tsp fine salt

Tomatoes

  • 300 g Roma tomatoes (about 3 medium), halved lengthways; or 200g cherry tomatoes, halved

Pork

  • 200 g minced pork (20% fat preferred)

For Cooking

  • 2 tbsp vegetable oil

Seasoning

  • 2 tbsp fish sauce (nam pla)
  • 1 tsp palm sugar or light brown sugar

To Serve

  • To serve: steamed sticky rice (khao niao), raw cucumber cut into batons, white cabbage in wedges, long beans cut into 5cm lengths, spring onion, deep-fried pork rinds (kaeb moo) optional but traditional

Method

  1. Char the tomatoes and aromatics: place the halved tomatoes, shallots, and unpeeled garlic cloves on a foil-lined grill tray under a hot grill for 5 to 8 minutes, turning once, until blistered and softened in places but not collapsing entirely. Peel the garlic once cool enough to handle. Alternatively, char directly over a gas flame on a wire rack, turning with tongs.
  2. In a large mortar, pound the drained soaked chillies with the salt until broken down into rough pieces. Add the roasted kapi, lemongrass, and galangal; pound until a rough paste forms. Add the charred shallots and peeled garlic; pound until fully integrated.
  3. Add the charred tomatoes and pound to a coarse paste, leaving visible chunks of tomato. The paste should have texture, not be entirely smooth.
  4. Heat the oil in a wok over medium-high heat. Add the pounded paste and stir-fry for 2 minutes until fragrant and slightly darkened.
  5. Add the minced pork. Press it firmly into the paste and stir-fry continuously, breaking the pork up and keeping it in constant contact with the paste, for 6 to 8 minutes until the pork is cooked through and the oil begins to separate visibly at the edges of the paste. The mixture will become drier and more aromatic as the moisture from the tomatoes evaporates.
  6. Season with fish sauce and palm sugar. Stir to combine. Taste: the relish should be hot, deeply savoury, lightly sweet, with a roasted edge from the tomatoes and chilli.
  7. Transfer to a serving bowl. Serve warm or at room temperature with sticky rice formed into small balls by hand, raw vegetables arranged around the bowl, and deep-fried pork rinds alongside.

Notes

Kapi (Thai fermented shrimp paste) is available in Thai and Southeast Asian food shops and is distinct from Malaysian belacan or Indonesian terasi in its softer texture and more intensely brined flavour; belacan is a workable substitute if kapi is unavailable. The entire paste can be prepared in a mortar or in a food processor; the mortar produces the best coarse texture. For a vegetarian version, omit the kapi and minced pork and substitute 150g of crumbled firm tofu, fried until golden before adding to the paste; the fermented depth will be absent but the tomato and chilli character remains.
