Place potatoes and enough water to cover in a 4-quart saucepan over high heat and bring to a boil. Reduce heat to low; cover and simmer 20 to 25 minutes or until potatoes are tender. Drain. Return potatoes to saucepan and shake over heat to remove excess moisture.
In a large bowl, mash potatoes well with a potato masher or fork, or put them through a ricer. In a small saucepan, heat milk, butter and TABASCO® Green Sauce until warm and stir into mashed potatoes along with parsley and salt; whip with a fork, whisk or electric mixer until light and fluffy. Serve immediately with mix-ins of choice.
