Soak the dried shrimp in warm water, to cover, for 10 minutes. Drain the shrimp, puree them in food processor or blender, and set aside.
Heat the 1/4 cup of dende oil or olive oil in a heavy skillet and saute the onions, garlic, jalapeno, cashews, almonds, and pureed dried shrimp for 10 minutes. Add the fish stock and coconut milk and simmer for 5 minutes.
Add the sea bass and poach it in the sauce for about 12 minutes until the fish is flaky. Add the raw shrimp and cilantro cook for another 4 minutes.
Drizzle with the remaining 1 tablespoon dende oil and serve with white rice.
