01 - Place peeled and chunked potatoes in a large pot and cover with cold water. Add 1 teaspoon salt.
02 - Bring water to a boil over high heat. Reduce heat to simmer and cook potatoes until very tender, about 15–18 minutes.
03 - Drain potatoes thoroughly and return them to the warm pot. Let steam dry for 1 to 2 minutes to remove excess moisture.
04 - Using a potato masher or ricer, mash potatoes until smooth and free of lumps.
05 - Gradually blend in warm milk, cream, and butter until the mixture is creamy and well combined.
06 - Adjust seasoning with additional salt and pepper as desired. Transfer to a serving dish and garnish with chopped chives or parsley if preferred. Serve hot.
