To make fungi, bring 2 cups water and 1 teaspoon salt to boil. Whisking constantly, gradually add cornmeal in thin stream. Reduce heat to low.

Add butter and okra. Add salt to taste.
In a wide saucepan, bring 8 cups water to boil. Add lime juice, and reduce heat to low. Add fish. Simmer 10 minutes, or until it flakes easily with fork. Drain well.
