This is the most popular steamed fish dish in Thailand, served with a spicy Thai chili pepper, garlic and lime juice sauce. In Asia fish is always steamed whole, but if you prefer to use fillets simply reduce the cooking time. Red chili peppers are mainly for added color, so if you have ripe Thai chili peppers (prik kee noo), omit the milder chilies. Best of all, steamed fish is one of the quickest and healthiest main dishes to prepare.
