Cut your fish into slices about 1.5 centimeters thick. If there are areas that need cleaning, clean them.
Place the sliced fish in a deep bowl. Pour the lemon and lime juice you squeezed over them, covering them all over. Put it in the refrigerator and marinate the fish in this way for 3 hours. As a result of marinating, the fish should have a matte appearance.
When the marinating time is over, remove the fish from the lemon juice and wait for it to drain for a few seconds, then place it in a new deep bowl. Pour the coconut milk over the fish. Add salt, chopped onions, chopped red peppers and chopped green onions. Mix until all ingredients are mixed together.
Spoon the mixture into the coconut shell. Add coriander leaves on top. Lastly, garnish with sliced lemons and serve. Bon Appetit!
