Nam Prik: A Regional Guide to Thailand's Chilli Dips

Curries and noodles get most of the attention abroad, but the dish that sits closest to the heart of everyday Thai eating is far simpler. Nam prik, which translates roughly as chilli water, is a family of pounded chilli dips and relishes eaten with rice, vegetables and fish. A small bowl of nam prik with a plate of vegetables is, for many Thai families, the most basic and most satisfying meal there is.

There are hundreds of versions. Every region, and in practice every household, has its own, and the dip changes with the season and with whatever is in the market. They range from loose, sharp, lime-heavy sauces to thick, smoky pastes. What they share is a base of chillies, usually garlic or shallots, and something salty and savoury.

How nam prik is eaten

Nam prik is rarely eaten on its own. It sits in the middle of the table with a spread of things to eat with it, and each mouthful is a combination of dip, rice and something fresh or cooked.

• Fresh raw vegetables (phak sot): cucumber, long beans, cabbage, Thai aubergines and fresh herbs.
• Blanched or steamed vegetables (phak luak): pumpkin, morning glory, okra, bamboo shoots and young leaves.
• Fried or grilled fish, especially in central Thailand.
• Pork crackling, boiled eggs or omelette, depending on the region.
• Rice: jasmine rice in the centre and south, sticky rice in the North and Isaan.

The vegetables matter as much as the dip. Their cool, crisp or bitter flavours balance the heat and salt of the nam prik, which is seasoned boldly for exactly that reason.

The basic method

Most nam prik follow a similar pattern, even when the ingredients differ:

1. Roast or grill the chillies, shallots and garlic, often in their skins, until soft and charred in places. Some fresh dips skip this step and use everything raw.
2. Peel the roasted aromatics and pound them in a mortar with a little salt.
3. Add the savoury element, such as shrimp paste, fermented fish, dried shrimp or grilled fish, and pound again.
4. Season with fish sauce, lime juice or tamarind, and sometimes a little palm sugar, tasting as you go.
5. Loosen with a little water if the dip is too thick, and serve with vegetables and rice.

Texture is part of the point. Nam prik is pounded rather than blended so that it stays rough, with small pieces that cling to vegetables and rice.

The North: nam prik noom and nam prik ong

Northern Thailand is home to two of the best-known nam prik in the country. Nam prik noom is made from long, pale green chillies (prik noom), grilled over charcoal with shallots and garlic until blistered, then peeled and pounded. The result is smoky, a little sweet and only moderately hot, with a soft, chunky texture. It is eaten with sticky rice, steamed vegetables and khaep moo, crisp puffed pork crackling, and it is a common sight in Chiang Mai markets.

Nam prik ong is quite different. It is a cooked dip of minced pork and tomatoes, simmered with a paste of dried chillies, shallots, garlic and shrimp paste or thua nao, a fermented soybean product used in the North. It is mild, savoury, slightly sour and bright orange-red, with a texture closer to a thick meat sauce than a dip. It is served with raw cucumber, cabbage and long beans, crackling and sticky rice, and it is a good introduction for anyone wary of chilli heat.

The Central Plains: nam prik kapi

Nam prik kapi is the classic central Thai version, built on shrimp paste (kapi). Raw garlic, bird's eye chillies and roasted shrimp paste are pounded together, then sharpened with lime juice and seasoned with fish sauce and palm sugar. Some cooks add pea aubergines (makhuea phuang), which are crushed lightly so they burst with a bitter crunch. The dip is pungent, sour and hot, and quite runny.

Its classic partner is pla thu, a small mackerel that is steamed and then fried until crisp. Together with a plate of raw and blanched vegetables and sometimes a slice of omelette made with cha-om, a feathery green leaf, it makes up one of the best-loved home meals of central Thailand.

Central Thai cooking also produces nam prik pao, a sweet and smoky roasted chilli paste that is fried in oil and used as a relish, a spread and an ingredient in tom yum and stir-fries.

Isaan: jaew

In the Northeast, chilli dips are usually called jaew, a word shared with neighbouring Laos. They are typically simpler, drier and hotter than central versions, and they are eaten with sticky rice, rolled into a small ball and dipped.

Jaew bong is a thick, dark, intensely savoury paste made with roasted chillies, shallots, garlic and galangal, pounded with pla ra, the fermented fish that runs through Isaan cooking. Jaew mak len is made with grilled tomatoes, giving a softer, sweeter dip. Nam jim jaew, the version most visitors meet, is a thinner dipping sauce of fish sauce, lime, roasted chilli flakes and toasted rice powder, served alongside grilled chicken and pork.

The South

Southern Thai food is known for its heat, and its chilli dips are no exception. In the South they are often called nam chup rather than nam prik. Shrimp paste is widely used, as the region has a long coastline and a strong tradition of preserved seafood. Nam prik kung siap, made with smoked dried prawns, is associated with the Andaman coast around Phuket and Phang Nga.

Southern meals usually come with a generous plate of fresh vegetables and leaves to cool the heat, including sator (stink beans) and other local greens, as well as cucumber and long beans.

Making it part of the table

A bowl of nam prik is one of the easiest ways to make a simple meal feel Thai. Start with a mild one such as nam prik ong or nam prik noom, add a plate of the freshest vegetables you can find, and cook plenty of rice. Once the method feels familiar, it is easy to vary: more lime, less chilli, a different fish. That flexibility is exactly why nam prik has stayed at the centre of Thai home cooking.
