Peel and dice the potatoes into 2 inch cubes. Rinse and set aside.
Bring a pot filled half way with water to boil. Add in the salt and potatoes and cook until they are fork tender (enough to easily insert a fork)
Drain the water and return potatoes to pot. Add in the butter, salt to taste, sour cream, hot milk and mash well with a potato masher until you obtain and very creamy texture. Note, if you are adding garlic, melt the butter and garlic together at the same time to infuse the garlic flavor.
Allow to simmer for a few minutes on low heat.
Remove and transfer the mashed potatoes to a serving bowl. Drizzle 2 tbsps. of melted butter on top and then crack some fresh ground pepper on top.
Garnish with some chopped chives and serve.
