Salt-cod balls are ubiquitous in Brazil's bars and restaurants, but they're a snap to make at home. If you don't have the time to soak the salt cod for at least 48 hours, you can use fresh cod. Bake it at 375 F until it's cooked through and flakes easily with a fork (about 15 to 18 minutes). Then add 1½ teaspoons of salt and follow the rest of the recipe.
