Bhutanese cooking rests on a fact that surprises most visitors: chillies are treated as a vegetable, not a spice. They are the main ingredient of the national dish, eaten by the handful, and dried in bright red sheets across roofs and hillsides every autumn.
Ema datshi
Ema datshi — chillies and cheese — is the national dish and appears at nearly every meal. Whole or split green chillies are stewed in a sauce of local cheese, datshi, which is soft and slightly sour. It is genuinely hot. The family of variants runs deep: kewa datshi with potato, shamu datshi with mushrooms, and, for anyone struggling, versions with more cheese and fewer chillies.
Rice is the base of the meal, and in the highlands it is the local red rice, nutty and slightly sticky, grown in the Paro and Punakha valleys. Buckwheat replaces it in Bumthang, as noodles (puta) or pancakes (khule).
The rest of the table
Momos — steamed dumplings filled with beef, pork or cheese — are the universal snack. Phaksha paa is pork belly stewed with dried chillies and radish. Jasha maroo is a spiced chicken stew, one of the milder options. Dried beef and dried fish appear constantly, a legacy of preserving food through long winters. Ferns, nettles and river weed show up seasonally.
Drinks
Suja is butter tea — tea churned with butter and salt, closer to a thin broth than a drink, and an acquired taste that makes complete sense at altitude. Ngaja is the sweet milk tea served to visitors. Ara is the home-distilled spirit made from rice, wheat or barley, sometimes served warm with a fried egg in it. Beer is widely available and largely domestic.
What to expect as a visitor
Hotel buffets aimed at tourists tone the heat down substantially and add Indian, Chinese and continental dishes. If you want the real thing, say so — most cooks will happily make a proper ema datshi, and most visitors find one plate is enough to understand. Ask for it alongside milder dishes rather than instead of them.
Vegetarians do well here: Buddhism means meat-free cooking is normal, cheese and vegetable dishes dominate, and many Bhutanese avoid meat entirely on certain days of the lunar calendar, when butcheries close.
One custom worth knowing: doma, betel nut wrapped in leaf with lime paste, is chewed widely and offered as a courtesy. It stains the mouth red and is considerably stronger than it looks.
