In a large makeshift steamer, bring the court bouillon to a simmer over moderate heat.

Add the fish and steam for 10 minutes per inch of thickness. If necessary, cook thicker pieces such as cod first, and add thinner fillets such as bass or weakfish after a few minutes, so that all will be cooked at the same time.

When all the fish is in the steamer, place the scallions over the fillets.

While the fish is cooking, add the lima and string beans to the corn, stirring from time to time. Stir in the cream to loosen the mixture.

Pour the succotash on a heated platter, then arrange the fish and rendered salt pork over the succotash.
