The primary ingredient in mashed potatoes is, unsurprisingly, potatoes. Commonly used varieties include Russet or Yukon Gold, known for their starchy texture, which results in a creamy and fluffy consistency when mashed. To prepare mashed potatoes, the potatoes are typically peeled, boiled until tender, and then mashed with various additions such as butter, milk, salt, and pepper for flavor. This classic side dish complements many meals and is particularly popular during holidays and family gatherings. Its versatility allows for variations, such as adding garlic, cheese, or herbs, enhancing its taste and appeal.
