Tom klong (smoky sour dried-fish soup)
Tom klong is the older, rustic cousin of tom yum, cooked in central Thai homes along the rivers of Suphan Buri and Ang Thong, where fish was dried and smoked to keep through the rains. Shallots, garlic and dried chillies are charred first, then simmered with tamarind, lemongrass and galangal, and smoked dried fish turns the clear broth deep and savoury. It is sour, smoky and hot, eaten with rice and a plain omelette. Look for dried smoked fish (pla krob or pla salid) in Asian grocers, or use smoked mackerel. Chef's tip: grill the aromatics until blackened in patches; pale, raw shallots give a thin soup without the smoke that defines it.
