Instructions

  1. Step 1: Bring a large pot of salted water to a boil. Add 2 lbs peeled and diced potatoes and cook for 15-20 minutes until fork-tender, then drain thoroughly.
  2. Step 2: While potatoes cook, mince 3 cloves black garlic and set aside. Melt 3 tbsp butter in a small saucepan over medium heat, then add the minced black garlic and cook for 1 minute until fragrant.
  3. Step 3: Return the drained potatoes to the pot and add the butter-black garlic mixture, 1/4 cup warmed milk, 1/2 tsp salt, and 1/4 tsp black pepper. Mash until smooth, adding more milk if needed to reach a creamy consistency.
  4. Step 4: Transfer to a serving bowl and let rest for 5 minutes before serving.
