Crush chilis in a bowl. Add sea salt and continue crushing until the juices are released into the salt. The more you crush, the more heat you add to the mixture, so beware! For a more smoky flavor sprinkle in some paprika. Let the chili juices dry out in the salt mixture for about 1 hour.
Use as a dipping condiment for green mangoes or in any recipe to enhance it's salt and spicy flavors.
