Salt, pepper and lime is a sauce that they make in Vietnam to go with all sorts of fish dishes. It is so easy to do and makes any fish taste electric.
Squeeze a quarter of a lime on top of ground salt and pepper (black pepper is necessary, but I like to use a combination of black and white pepper for more complexity). Then serve in tiny bowls next to your fish dishes.
This sauce goes especially well with crustaceans like shrimp, lobster but also I love it with calamari.
This sauce works because it has so much energy and freshness. The pepper and the lime create electricity (energy) and exoticism.
