Ingredients:

2 pounds russet potatoes (about 4 medium), peeled and cut into 1-inch pieces
1 teaspoon kosher salt, plus more as needed
1/4 cup extra-virgin olive oil
1 teaspoon finely chopped basil
1 teaspoon minced flat-leaf parsley leaves
1 teaspoon minced fresh tarragon
Freshly ground black pepper

Cooking Recipe:

In a large saucepan, combine the potatoes, 1 teaspoon salt, and cold water to cover. Bring to a boil over high heat. Lower the heat to maintain a simmer (means to cook over a low fire) and cook until fork tender, about 10 minutes. Drain the potatoes (be sure to wash the dirt off the skin well before using) , reserving a 1/2 cup of the cooking liquid. Return potatoes to the pan. Shake the pan over medium heat for about a minute to dry the potatoes (scrape off the potato skin if recipe calls for it) . Transfer the potatoes to a food mill, ricer, or bowl.
Add the oil and reserved cooking liquid to the saucepan, and warm over medium heat. Remove pan from the heat. Mash the potatoes through the food mill, ricer, or by hand into the pan. Add the herbs and stir to combine. Season with salt and pepper to taste. Serve immediately.
