Take potatoes and rinse them off using warm water, before peeling their skin off. Now you can cut them into pieces. Make sure you cut each potato into 5 to 6 equal chunks. Rinse the chunks off.
While you work on cutting chunks of potatoes, you can take a pot of water and place it over medium heat. Wait for the water to reach the boiling point, before you add in chunks of potatoes.
Cook the potatoes for 15 minutes or until they are tender enough to easily be pulled apart with a fork. Drain the potatoes and place them into a large mixing bowl.
You can now add 1 cup of milk into the mixing bowl (more or less depending on desired consistency), 4 tablespoons of butter, and salt and pepper, as per your taste preference.
Using a mixer, beat the ingredients on a high speed until the mixture is thoroughly smooth and blended. The mashed potatoes recipe is now ready to serve.
