Spatulatta.com Grandma's Creamy Mashed Potatoes Matt's grandma makes these yummy, creamy mashed potatoes. She says only use red potatoes, not white or yellow. The other key to her success is whipping the margarine in first, then adding the milk a little at a time until she gets the right consistency. After tasting them, we agree! Makes 6-8 servings You'll need: 3 pounds of red potatoes 1/2 cup of soft tub margarine 1/2 cup cold whole milk salt and pepper to taste Some adult help Equipment: Measuring cups A veggie peeler A sharp knife A cutting board A 4-quart pot A colander Oven mitts A large bowl Electric mixer Peel and quarter potatoes. Boil until soft (about 45 minutes). A fork should slide into them with ease. Ask for help draining the potatoes because the steam coming off them will be super hot. Put the potatoes in a big bowl. Add the margarine. Whip with electric mixer until lumps are gone. Add the milk a little at a time. Continue to beat until smooth.
