Nam prik prik Thai on: identify the peppercorns and prepare Sujitrar’s cooked dip

What this dip is and when to make it

Nam Prik Prik Thai On - Chili Dip with Green Pepper is an English label for a Central Thai chili dip built on fresh young peppercorns. At its core it is pounded in a mortar from green peppercorns, chilies, garlic and shrimp paste, and cooks add other ingredients according to their own version. Like other nam prik, it is served as a dip alongside vegetables.

This guide follows one complete cooked version, credited to the cook Sujitrar, that turns the pounded base into a richer dip with minced pork and tomato. Make it when you want a nam prik substantial enough to anchor a vegetable platter rather than a small, sharp condiment.

Identify the dish and the peppercorns

The Thai name is น้ำพริกพริกไทยอ่อน. A literal English gloss is young peppercorn chili dip. “Nam prik prik Thai on” is one romanization of that name, so expect other spellings on menus and in recipes.

The “green pepper” in the English title means fresh young peppercorns, not bell pepper. Thai recipes list the peppercorns as พริกไทยอ่อนรูดเม็ด, meaning young peppercorns stripped from their stems, and they appear as a separate ingredient from the chilies. Before you start, strip the peppercorns from their stems and weigh or measure the loose peppercorns.

Two versions you may find: cooked and mortar-only

Recipes under this name are not all the same preparation. Sujitrar’s version is cooked in a pan with pork and tomato. A separate version published by KRUA stays in the mortar and has no heating step. Decide which one you are making before you shop.

Feature	Sujitrar’s cooked dip	KRUA’s mortar-only dip
Thai name	น้ำพริกพริกไทยอ่อน	Same dish name
Peppercorns	60 g stripped young peppercorns	1 tbsp peppercorns
Chilies	1 tbsp bird chilies, plus 1 red long chili and 1 green or yellow long chili	1 red bird chili
Mortar stage	Chilies, garlic and shrimp paste pounded together	Garlic and shrimp paste pounded fine, then chili; peppercorns lightly crushed
Pan stage	Paste fried in oil, then pork, tomato, peppercorns and seasonings	None specified
Main additions	Minced pork, tomato, tamarind liquid	None beyond seasonings
Seasonings	Palm sugar, fish sauce, tamarind liquid	Fish sauce, palm sugar, lime juice

For reference, KRUA’s mortar-only formula uses 7 peeled Thai garlic cloves, 2 tsp shrimp paste, 1 red bird chili, 1 tbsp peppercorns, 2 tsp fish sauce, 1 tsp palm sugar and 1 tsp lime juice. The garlic and shrimp paste are pounded finely, the chili goes in next, the peppercorns are lightly crushed, and the seasonings are stirred in. Do not mix its steps or quantities into the cooked recipe below.

Ingredients for Sujitrar’s cooked dip

Minced pork: 300 g
Stripped young peppercorns: 60 g
Bird chilies: 1 tbsp
Garlic: 1 tbsp
Long chilies: 1 red and 1 green or yellow
Tomato: 1 large
Shrimp paste: 20 g
Oil: 2 tsp
Palm sugar: 3½ tsp
Fish sauce: 2 tsp
Tamarind liquid: 4 tsp
Water: a little, optional
Vegetables for serving

The recipe does not give a yield or say how the tomato should be cut, so plan portions and tomato prep to suit your table.

Equipment

Mortar and pestle for the chili paste
A pan for frying the paste and cooking the pork
An instant-read food thermometer for checking the pork
Shallow containers if you plan to keep leftovers

Method, in order

1. Pound the chilies, garlic and shrimp paste together in the mortar. The peppercorns are not part of this stage.
2. Heat the oil in the pan, add the pounded paste and fry until it smells fragrant.
3. Add the minced pork and fry until it is nearly cooked.
4. Add the tomato.
5. Add the stripped peppercorns along with the palm sugar, fish sauce and tamarind liquid.
6. Keep cooking until everything is cooked through. Add a little water at this stage if you choose; the recipe treats it as optional and gives no amount.
7. Check the pork with a thermometer (see below), then serve with vegetables.

The order matters because each addition goes in on top of a specific state: the paste is fragrant before the pork goes in, and the pork is nearly cooked before the tomato and peppercorns follow. If the paste is not yet fragrant, keep frying before adding pork. If the pork is still clearly raw, wait before adding the tomato.

How to judge progress and doneness

The recipe gives no frying or simmering times, so rely on cues rather than the clock. The first cue is aroma: the fried paste should smell fragrant before you add the pork. The second is the pork reaching a nearly cooked state before the tomato goes in. The final cue is that the whole mixture is cooked through.

Because the dip contains ground pork, confirm the final stage with a food thermometer rather than by eye. Color alone does not show that meat is safely cooked. Ground pork should reach 160°F (71°C). This number comes from US food-safety guidance, not from the recipe author. Insert the thermometer into the center or thickest part of the mixture and follow your thermometer’s instructions. If the reading is below 160°F, keep cooking and check again.

Storing and reheating leftovers

Refrigerate leftovers in shallow containers within 2 hours of cooking, or within 1 hour if the room or outdoor temperature is above 90°F. Keep them at 40°F or below and use them within 3 to 4 days. Reheat leftovers to 165°F before serving.

Example: scaling to a half batch

This is an illustrative calculation, not a tested variation. To make half the recipe, multiply every ingredient by 0.5. The arithmetic tells you quantities only; it does not establish how many people the dip serves or how long it takes to cook.

Ingredient	Full recipe	Half batch
Minced pork	300 g	150 g
Stripped young peppercorns	60 g	30 g
Shrimp paste	20 g	10 g
Bird chilies	1 tbsp	1½ tsp
Garlic	1 tbsp	1½ tsp
Long chilies	1 red, 1 green or yellow	½ red, ½ green or yellow
Tomato	1 large	½ large
Oil	2 tsp	1 tsp
Palm sugar	3½ tsp	1¾ tsp
Fish sauce	2 tsp	1 tsp
Tamarind liquid	4 tsp	2 tsp
