Tom's Perfect Mashed Potatoes

Ingredients

• 2 lb. Idaho potatoes
• 3 tbsp. Kosher salt
• 1 c. milk
• 4 tbsp. cold unsalted butter
• ½ tsp. fresh-ground black pepper

Directions

1. Cook the potatoes: Heat oven to 250 degrees F. Place the potatoes in a pot and fill with enough water to cover. Add the salt and bring to a boil over high heat.
2. Reduce the heat to medium and simmer until potatoes are tender -- 12 to 15 minutes. Drain the potatoes, transfer to a baking pan, and place in the oven until thoroughly dried out -- 7 to 8 minutes. (Shake the pan occasionally to ensure all excess water evaporates.)
3. Puree the potatoes: Heat the milk in a small saucepan until it simmers. Mash the potatoes until smooth, taking care not to overwork them. Alternately add the butter and milk in thirds -- gently folding with a rubber spatula. Stir in the pepper.
