In a medium saucepan cook potatoes, covered, in a small amount of boiling water for 30 to 35 minutes or until very tender; drain. Mash with a potato masher or beat with an electric mixer on low speed.
Add maple syrup, margarine or butter, and salt. Gradually beat in enough half-and-half, light cream, or milk to make potato mixture light and fluffy. Pipe or spoon potato mixture onto serving plates. Makes 6 side-dish servings.
