Kaeng Khae — Northern Forest Herb Curry / แกงแค

Northern Thai (Lanna) — one of the most ancient Northern curry forms; reflects the forest-gathering food culture of the Lanna Kingdom

Gaeng khae is one of the oldest Northern Thai curry preparations — a thin, no-coconut broth flavoured with a paste of dried chillies, galangal, lemongrass, and shallots, cooked with whatever seasonal forest vegetables, herbs, and protein (often freshwater fish, frogs, or snails) are available. The defining characteristic is the use of wild plants and herbs not found in Central Thai cooking: dok khae (Sesbania grandiflora flowers), acacia leaves (cha-om), phak wan (Melientha suavis), and bamboo shoots. The broth is light, herbal, and mildly hot — it is not a complex curry in the sense of massaman or panang, but rather an expression of the Northern Thai forest larder.

Gaeng khae is Thai cuisine's most direct connection to its pre-agricultural, forest-gathering heritage — the flavours of wild herbs, river proteins, and forest plants provide a window into how people ate before farming standardised the ingredient set.
