Nam Phrik Num (น้ำพริกหนุ่ม)

The Young Dip The North Keeps in the Fridge

น้ำพริกหนุ่ม takes its name from the chilli: phrik num, the "young" green chilli — big and mild, smaller than the phrik yuak, also called phrik hom or phrik on in different markets. Wongnai's pitch is almost a non-recipe: grill three things, peel them, pound them. No frying, no paste-building, nothing but fire and salt between the garden and the bowl.

And it's the base of everything else, as TrueID's northern-born author explains: northerners keep a batch in the fridge and take it to the fields with vegetables picked on the way. Re-pound the same dip with crab paste and it becomes nam phrik nam pu; with fish it becomes nam phrik pla; with meat, nam phrik jin. The plain version is the mother recipe of the whole family — which is why the sources argue hardest about what goes in it.

The craft is all in the fire. The chillies are grilled over a low flame until the skin blisters and chars — that char is the smoke that carries the whole dip — then peeled, and only the soft insides are pounded. TrueID's traditional version is salted and nothing else; other cooks add lime and fish sauce, pla ra, or a roasted aubergine. The essentials never change: grilled chilli, grilled shallot, grilled garlic, salt, mortar.

The Recipe (home version, from TrueID)

The lime version (Wongnai): 7 phrik num, 4 shallots, 10 garlic cloves, 1 tsp salt, 1½ tbsp fish sauce, 2 tbsp lime juice — plus a little sugar when seasoning. The pla ra version (Wongnai, user niumo): 15 chillies, 9 shallots, a head of garlic, ¼ tsp salt, 1 tbsp pla ra, bird's eye chillies if the num runs mild. The aubergine version (TrueID): add a whole Thai aubergine, grilled and peeled alongside the chillies.

The Method

1. The grill (chillies). Young chillies over a low fire, turned until the flesh cooks through and the skin blisters and chars lightly — the char is the point. No grill? A dry pan over a low flame works.
2. The grill (aromatics). Garlic and shallots take the same low fire until cooked, with skins lightly charred.
3. The peel. Cool until you can handle them, then peel away the burnt skins — keep the soft insides.
4. The pound. Salt into the mortar first, then chillies, garlic and shallots. Pound coarse — rough and chunky, not puréed.
5. The bowl. Spoon it up and eat with pork crackling, fresh vegetables, or boiled eggs — or hold it for the fridge, the way the north does.

Where Thai Sources Disagree

How Western Versions Get It Wrong

• Roasting red bell peppers. The phrik num is a young green chilli — grassy, mildly hot, smoky after the fire. A bell pepper is sweet and fleshy; the dip that results is a different food.
• The "green salsa" treatment. Lime, tomato, coriander and a blender turn it into salsa verde. The classic is chilli, shallot, garlic and salt — no tomato, lime only in some versions, and always pounded, never blitzed.
• Puréeing it smooth. The texture is a coarse pound, pieces still visible. A food processor makes a smooth green purée and kills the structure.
• Serving it fridge-cold as a condiment. It's eaten warm or at room temperature, right after the pounding, with vegetables and pork crackling — not drizzled from a bottle.
• A light sear instead of a char. The blackened skin is half the flavour. A quick blanch or a gentle sear gives none of the smoke, and peeling the char is the step that concentrates it.
• Deseeded jalapeños for "mild heat". Jalapeños have a different flavour entirely; the mildness of phrik num comes from the variety, not the deseeding.

UK Ingredient Notes

• Phrik num are the one hard find: Thai grocers carry them fresh (often labelled simply "Thai green chillies — large"). Mild long green chillies — Turkish sivri or padrón — are the closest substitute; jalapeños are not.
• Thai shallots: the small pink shallots at Thai grocers; banana shallots work well and are everywhere.
• The salt-only version needs nothing else — chilli, shallot, garlic, salt, all from any supermarket or grocer.
• Pla ra (fermented fish sauce) for the niumo version, from Thai grocers; fish sauce and lime for the Wongnai version are standard.
• Pork crackling: pub pork scratchings do the job surprisingly well; or crisp strips of pork belly skin in the oven.
