Stir the coconut, evaporated milk, sweetened condensed milk, eggs, sugar, and salt together in a bowl; pour into a round 3-quart baking dish. Set the baking dish into a large roasting pan. Pour enough water into the bottom of the roasting pan to fill about halfway up the side of the baking dish. Carefully move to the preheated oven.
Bake in preheated oven until a toothpick inserted into the center comes out clean, about 60 minutes. Allow to cool completely before serving.
