Vegan vs เจ: Thailand's plant-based tradition
There are two words on our sign: “vegan” and “เจ”. Travellers usually ask about the second one. Thai guests rarely ask at all — they grew up with it. Here is the short version of what เจ means.
Where เจ comes from
เจ (pronounced “jay”, sometimes written “jeh”) is Thailand’s own plant-based food tradition. It arrived with Chinese immigrants and, as far as we understand it, has roots in Chinese Buddhist and Taoist practice — we are cooks rather than historians, so we will stick to what every Thai kitchen knows in practice.
The tradition is most visible during the Nine Emperor Gods Festival, known in Thailand as เทศกาลกินเจ — usually translated as the “Vegetarian Festival”. For nine days, typically falling around October (the dates follow the lunar calendar and shift a little each year), many Thai and Chinese-Thai families “gin jay” — eat jay — and yellow flags with a red เจ character appear on food stalls all over the country. Phuket’s celebration is the famous one, but you will see the flags in Pattaya too.
What counts as เจ
During observance, เจ is stricter than the Western idea of vegan. Jay food contains:
- no meat, no seafood and no animal products of any kind — which rules out fish sauce, oyster sauce, shrimp paste, egg and dairy;
- and, on top of that, no pungent vegetables — garlic, onions, chives, shallots and other strong-smelling plants, which the tradition holds to be stimulating.
Practice varies from family to family, and some observers avoid further things besides, but “vegan minus the pungent vegetables” is a fair everyday summary.
เจ, มังสวิรัติ and vegan
Thai has a separate word for vegetarian: มังสวิรัติ (mangsawirat). A mangsawirat eater takes no meat, but may still take egg, dairy or honey — it depends on the person. Western vegan drops all animal products but keeps garlic and onion. เจ drops all animal products and the pungent vegetables too.
So, in purely food terms: every jay dish is vegan by definition, but not every vegan dish is jay.
Why a เจ kitchen is automatically safe for vegans
The ingredients that most often catch vegans out in Thai kitchens — fish sauce in the dressing, oyster sauce in the stir-fry, shrimp paste in the curry paste, egg in the noodles — all break เจ as well. A cook preparing real jay food has already removed every animal ingredient a vegan avoids, without being asked.
One honest caveat: during the festival, some regular restaurants add a เจ corner to the menu while still cooking meat in the same woks. If cross-contact matters to you, it is worth asking anywhere. A fully plant-based menu removes animal ingredients from the recipes, but guests with severe allergies should still ask about the kitchen’s current cross-contact process.
Our kitchen cooks เจ year-round
That last kind is us. We are a small family cafe in Pattaya, and our menu is 100% plant-based every day of the year — no fish sauce, egg or dairy in the recipes, festival or no festival. Dishes on our menu that carry the เจ badge — the red curry, pad thai and mushroom pad krapao — are cooked jay-style. If you keep the observance strictly or have specific ingredient requirements, ask the team about ingredients before ordering.
If you read Thai, the Thai menu lists every currently available dish. For Indian guests comparing pure veg and Jain-friendly food, we also keep a separate pure veg guide for Pattaya. And if you are simply hungry, the menu with real prices is the best place to start.
