Nam jim seafood (green chilli-lime dipping sauce)
Seafood grills along the beach at Bang Saen and Hua Hin set a little bowl of this bright green sauce by every plate of grilled prawns, squid and crab. It is pounded, not blended, from garlic, green bird's-eye chillies and coriander root, then loosened with lime and fish sauce until it is sharp, salty, hot and barely sweet. Make it no more than a few hours ahead. For a vegetarian version to eat with grilled vegetables and tofu, use 2½ tbsp light soy sauce instead of the fish sauce. Chef's tip: don't use bottled lime juice; its flat, bitter edge takes over a sauce this simple.
