- 1 medium head garlic
- 1 teaspoon olive oil
- 12 potatoes
- 1 cup butter, softened
- 4 teaspoons wasabi powder
- water as needed
- 1/2 cup milk
- salt and pepper to taste
- Preheat oven to 400 degrees F (200 degrees C).
- Remove papery outer skin of garlic bulb. Rub with olive oil and place on a small baking sheet. Bake in preheated oven for 45 minutes, or until skin can be easily pierced with a fork.
- While garlic is roasting, peel and quarter the potatoes. Place in a large pot and cover with water. Bring to a boil and allow potatoes to simmer until very soft, about 20 minutes. Drain water and mash potatoes with butter until smooth and fluffy.
- Squeeze softened garlic cloves out of skin into pot; in a small bowl, mix wasabi powder with just enough water to form a thick paste. Mash garlic and wasabi paste into potatoes, pour in milk and continue to mash until mixture is light and fluffy; season with salt and pepper to taste and serve hot.
