How to Make Potatoes Creamier: Add 2 Tbsp. milk to the drained cooked potatoes along with the margarine and sour cream.
Know How: Avoid using an electric mixer for mashing potatoes. The biggest drawback with electric mixers is that they can over work the potatoes to the point that the starch breaks down. It will result in mashed potatoes that are sticky and have a gummy consistency.
Special Extra: Add 1 tsp. minced garlic to drained cooked potatoes along with the margarine and sour cream.
