2 pounds all-purpose potatoes, preferably Yukon Gold (about 6 medium potatoes), peeled and cut into chunks
6 cloves garlic, peeled
Salt, to taste
2 teaspoons extra-virgin olive oil
1 cup buttermilk
1 tablespoon minced fresh parsley
1 tablespoon minced fresh chives
1 teaspoon minced fresh thyme
Freshly ground white or black pepper, to taste
Place potatoes and garlic in a large heavy saucepan. Add water to cover and season with salt. Bring to a boil. Reduce heat to medium, cover, and cook until potatoes are very tender, 10 to 15 minutes.
Meanwhile, heat oil and buttermilk in a small saucepan over low heat until just warm. (Do not overheat or it will curdle.)
When potatoes are done, drain in a colander and return to the pan. Place pan over low heat and shake for about 1 minute to dry potatoes.
Mash the potatoes and garlic with a potato masher, an electric hand-held mixer or by working through a ricer. Add enough of the buttermilk mixture to make a smooth puree. Stir in the parsley, chives and thyme, season with salt and pepper and serve.
