Central Thai — particularly associated with seafood stir-fry in Bangkok and coastal Central Thai cooking
Pad cha is a fiercely aromatic stir-fry built on fingerroot (krachai, Boesenbergia rotunda), green peppercorns on the vine, fresh chillies, holy basil, and kaffir lime leaf. It is applied almost exclusively to seafood — whole fish, squid, prawn, or shellfish — and produces an intensely fragrant, slightly peppery result that the floral, medicinal krachai uniquely achieves. The dish is named for the sound of the ingredients hitting the wok (cha = the sizzle-splash sound). Krachai julienned into thin strips is the signature textural element — it should be visible and slightly crispy. The heat level is high; this is not a mild stir-fry.
Pad cha's krachai-green peppercorn-holy basil fragrance is one of the most distinctive flavour signatures in Thai cooking — it smells like nothing else and is immediately identifiable at the wok station.
{"Krachai julienned into thin strips — not pounded, not pureed; the textural contribution of the fresh rhizome is essential","Fresh green peppercorns still on the vine — dropped in whole to blister in the wok","Seafood for maximum fragrance interaction — the delicate flavour of seafood is amplified by krachai's camphor-floral character","Holy basil added last","Very high heat — the whole point of the sizzle-splash name"}
Fresh krachai (fingerroot) has a distinctive appearance — small yellow-gold rhizome fingers emerging from a central knot. It is available frozen at Thai grocery stores. Do not confuse with galangal, which is much larger and harder.
{"Substituting galangal or ginger for krachai — neither produces the same camphor-floral medicinal note","Using dried green peppercorns — they don't blister the same way and deliver heat differently","Cooking fish fillets that break apart — use whole fish, thick steaks, or robust seafood like squid and prawn","Under-heating the wok — pad cha loses its identity without the char and smoke"}
