1) Unpeeled Potatoes: You may use unpeeled potatoes if you prefer.
2) Use Starch Potatoes: If you want fluffy mashed potatoes, use starchy potatoes like Russets or Yukon Golds. Don't substitute it with other types of potatoes.
3) Doubling the Recipe: Yes, you can double this recipe. The timing will stay the same. If you are tripling the recipe or the potatoes are packed too tightly, you may have to increase the cooking time by 1 - 2 minutes.
