Nam Phrik Ong (น้ำพริกอ่อง)

The Dip That Fries Its Paste

น้ำพริกอ่อง is the exception in the northern nam phrik family. Every other dip is pounded and left raw; this one is fried — Wongnai's pitch is a bowl of juicy tomatoes and fatty minced pork, hot and slightly sweet, that finishes with a fry until the tomato turns to sauce around the meat. It eats with sticky rice, fresh vegetables and pork crackling, and it's the dip northerners living in Bangkok say they miss most.

The technique has two moments worth keeping. The paste is pounded first — dried chillies, shallots, garlic, salt and the fermented element — then fried in oil until it smells, before anything else goes in. The tomato goes in late, once the pork is nearly cooked, and is fried until it collapses (ผัดจนมะเขือเทศสุกเละ): that collapse is the sauce. Water goes in a splash at a time, only if the pan runs dry, and the final seasoning is sugar and fish sauce — Wongnai's version says the sugar is optional if you don't have a sweet tooth.

Then there's the fermented question, the most argued part of the recipe. The northern original uses thua nao — a disc of fermented soybeans, toasted over the flame and pounded in; Aroifin toasts it before it enters the mortar. Cooks elsewhere swap in shrimp paste (Wongnai's home version), tao jiao yellow bean paste (Kapook's recipe for Thais abroad who cannot find thua nao), or both fermented pastes at once (TrueID). And the shortcut school skips the mortar entirely and opens a jar of red curry paste — nine steps, done.

The Recipe (home version, from Wongnai)

The thua nao version (Aroifin): 300 g minced pork, 500 g orange tomatoes, 30 g shallots, 10 g garlic, 20 g soaked dried spur chillies, 1 toasted thua nao disc, 8 g salt, 10 g sugar, 20 g rice bran oil, 1 cup water. The tao jiao version (Kapook): 500 g pork, 1 cup tomatoes, 5–8 garlic cloves, 5 shallots, 1 tbsp coriander root, 1 tsp kapi, 1 tbsp tao jiao, 2–3 tbsp fish sauce, 1 tbsp palm sugar, 1–2 tbsp tamarind water, 2 tbsp oil. The pork-belly version (TrueID): 500 g pork belly, 700 g sida tomatoes, 50 g garlic, 100 g shallots, 4 coriander roots, 10 dried jinda + 5–10 dried spur chillies, 1 thua nao disc, 1 tbsp kapi, ½ tbsp salt, 100 ml water.

The Method

1. The paste. Shallots, garlic, dried chillies, salt and shrimp paste into the mortar; pound until fine.
2. The fry. Oil in the wok, the second head of garlic bruised and fried until pale gold; the paste follows and fries until it smells.
3. The pork. Minced pork in; stir-fry it through the paste, adding a splash of water only if it looks dry.
4. The tomato. Once the pork is nearly cooked, the tomatoes go in and fry until they collapse into the meat — that collapse is the sauce.
5. The season. Sugar and fish sauce to taste; skip the sugar if you want it less sweet.
6. The bowl. Off the heat, topped with chopped spring onion and coriander; serve with fresh vegetables, pork crackling and hot rice.

Where Thai Sources Disagree

How Western Versions Get It Wrong

• The "Thai bolognese" framing. It looks like a meat sauce and gets spooned over pasta in western takes. It's a nam phrik — a dip, eaten by the spoonful with raw vegetables and sticky rice, not a sauce to drown a plate.
• Sweet chilli sauce for the "chilli" part. The heat is dried chillies pounded into a paste and fried — a bottle of sweet chilli sauce is a different food entirely.
• Fresh chillies instead of dried. The northern paste is built on dried chillies, which give the deep red-brown colour and the slow heat; fresh ones give salsa, not nam phrik ong.
• Passata and tinned tomatoes. The recipe's soul is whole fresh tomatoes fried until they collapse into the pork — tinned passata skips the fry and lands in a different dish.
• Lean turkey mince. The fat is functional: Aroifin's 10–20% fat keeps the dip soft and glossy. Lean mince dries to crumble.
• Skipping the fermented element. Kapi, thua nao or tao jiao — one of them is the depth of the dish. Chilli-garlic-tomato-pork without it tastes thin by comparison.

UK Ingredient Notes

• Pork mince: standard British 20% fat pork mince is exactly what the recipe wants — no special order needed.
• Dried red chillies: big bags at Thai grocers (spur or jinda types); dried bird's eye work but run hotter, so use fewer.
• Shrimp paste (kapi): any Thai grocer. Thua nao discs are hard to find in the UK — Tao jiao (yellow bean sauce, from the same shelf as black bean sauce) or kapi are the accepted swaps.
• Tomatoes: cherry tomatoes all year in supermarkets; use the best plum or on-the-vine ones you can find to stand in for the northern orange tomato.
• Tamarind block and palm sugar are Thai-grocer staples for the Kapook mother's version; fish sauce everywhere.
