This flan—Spanish baked custard—is best when made with leftover sweet potatoes that have been simply prepared and minimally seasoned. Use ground nutmeg in place of grated whole nutmeg, if you prefer. Kitchen Tip: Do not stir the sugar and water mixture during cooking because this causes the sugar to seize, or crystallize, which will make it difficult to pour.
