Larb, nam tok, grilled chicken, sticky rice and jaew: ordering Isan, cooked

Larb, nam tok, grilled chicken, sticky rice and jaew are one of the most common Isan spreads. Larb and nam tok share almost the same dressing; the difference is the meat: minced fine for larb, grilled whole and sliced for nam tok. The one word you must say clearly when ordering is “suk” (cooked), because Isan and northern menus also include raw larb, blood larb and koi, which Thailand’s Department of Disease Control warns about for Streptococcus suis infection and liver fluke.

The previous article covered som tam styles. These are the dishes that usually arrive next to it.

Larb and nam tok: the meat is the difference

Larb (ลาบ) is minced meat tossed in a dressing. Pork, chicken, duck, beef and fish are all used, and some recipes add skin or offal. It is seasoned with lime, fish sauce, chilli flakes, khao khua (toasted rice), shallots, spring onion and mint. Some places use pla ra instead of, or as well as, fish sauce.

Nam tok (น้ำตก), literally “waterfall”, uses the same dressing, but the meat is grilled in one piece and then sliced thin, so it tastes of the grill. There are several stories behind the name, such as the juices dripping and hissing on the coals, but no single agreed origin.

Khao khua (ข้าวคั่ว) is the heart of both: sticky rice toasted until golden and pounded coarse, for a nutty smell and a slight crunch.

	Larb	Nam tok
Meat	minced fine	grilled whole, then sliced
Aroma	toasted rice, herbs	toasted rice, grill smoke
Doneness	cooked in the pan (larb suk) or raw (larb dib)	depends on the grill; some places grill beef pink
Heat from	chilli flakes	chilli flakes

Grilled chicken, sticky rice, jaew

Sticky rice (khao niao, ข้าวเหนียว) is the Isan staple. You eat it by hand: roll a small ball, dip it, use it to pick up larb, and wipe up the dressing at the end. The basic Isan meal people eat most is larb, grilled chicken (gai yang, ไก่ย่าง), som tam and sticky rice, with fresh vegetables on the side.

Jaew (แจ่ว) is the Isan chilli dip, the counterpart of the Central region’s nam prik. It is made from pla ra, chilli, garlic and shallots, with sourness from lime or tomato, and eaten with blanched vegetables, fish and sticky rice. The dipping jaew served with grilled chicken or grilled meat varies by place. Since many jaew recipes contain pla ra, the cooked pla ra advice in the som tam article applies here too.

Worked example: ordering larb at the right heat

Larb is mixed one plate at a time, like som tam. Here are the per-plate amounts from one published nam tok recipe (linked in the sources):

• 250 g grilled meat
• 1 tbsp khao khua
• 2 tbsp fish sauce
• 1.5 tbsp lime juice
• 1 to 2 tbsp chilli flakes
• 5 small shallots

The chilli flakes range from 1 to 2 tbsp, a twofold difference in the same dish. That is why “medium” differs so much between places. Order by proportion instead:

1. If you take a little heat, say “phrik khrueng diao” (half the chilli). The cook uses about half the usual amount: if they normally put 2 tbsp, you get about 1.
2. If you take none, say “mai sai phrik” (no chilli) and ask for chilli flakes on the side for others at the table.
3. Always add “larb suk” (cooked larb), or for pork nam tok, “yang suk suk” (grilled well done).

Full sentences you can use: “larb moo suk, phrik khrueng diao” (cooked pork larb, half chilli) or “nam tok moo, yang suk suk, mai sai phrik” (pork nam tok, well done, no chilli).

Raw larb, blood larb, koi: what the risk is

Isan and northern menus include dishes made with raw meat or raw blood, such as larb dib (raw larb), larb lueat (blood larb), lu and koi. The risk depends on the meat.

Raw pork and raw pig blood: Streptococcus suis. The bacterium lives in the airways and blood of sick pigs. The Department of Disease Control names raw pork larb and lu as risky dishes. From 1 January to 5 April 2022 there were 81 cases and 7 deaths. The infection can cause permanent deafness or death. People at higher risk include regular heavy drinkers and people with conditions such as diabetes, kidney disease or cancer, or without a spleen.

Raw freshwater fish: liver fluke. The Department of Disease Control lists koi pla, raw fish larb, raw fish phla, pla som and raw pla ra as risky. WHO notes that the International Agency for Research on Cancer classes this fluke (Opisthorchis viverrini) as Group 1, carcinogenic to humans, because of its link to bile duct cancer.

Lime, salt, fish sauce and tamarind do not cook food and cannot kill parasites. The Department of Disease Control is clear: only heat does.

If you have already eaten a raw dish, do not panic, but do not ignore it. With high fever, severe headache, a stiff neck or changes in hearing, see a doctor at once and say you ate raw pork. If you have often eaten raw freshwater fish, the Department of Disease Control advises a stool test; ask a doctor or local hospital.

Common mistakes

• Ordering just “larb” at a place that also serves it raw. You will usually get it cooked, but not everywhere. Saying “larb suk” costs nothing.
• Thinking lime “cooks” the fish. Fish that turns white in lime juice is still raw.
• Not asking about pla ra in larb and jaew. Some places season larb with pla ra; ask whether it is boiled.
• Eating sticky rice with a spoon. Not wrong, but rolling it by hand makes dipping and picking up larb much easier. Wash your hands first.

Summary

Larb and nam tok share a dressing and differ in minced versus grilled meat. Eat them with hand-rolled sticky rice, grilled chicken and jaew. Order heat as a share of the chilli flakes, and say “suk” every time: raw pork risks Streptococcus suis, raw freshwater fish risks liver fluke, and lime does not help. Next, the series heads north for khao soi and nam ngiao.
