The best potatoes for mashing are higher starch potatoes like u003cstrongu003eYukon goldsu003c/strongu003e (my favorite) or u003cstrongu003eRussetsu003c/strongu003e. These potatoes will result in the fluffiest, smoothest and most flavor-packed mash. Of course you can use other varieties of red or white skinned potatoes, but they will require more mashing in order for them to become creamy.
