Place potatoes, salt, and garlic in large pot; cover with water. Bring to a boil over high heat, then reduce heat and simmer for about 15-20 minutes or till fork tender.

Drain potatoes and mash with a potato masher. Add cream cheese, 4 tablespoons of the milk, butter, and pepper. Stir till well combined, then heat through over low heat. Add more milk if needed to get the consistency you want.

Taste and add salt to taste. I usually add about 1/2 teaspoon.
