Preheat oven to 425F degrees (218C).
Clean and dry the sweet potatoes, then rub all over with olive oil.
Place the potatoes onto a baking sheet, uncovered. Bake for 45 minutes, or until they are soft (insert a knife through).
Let cool for 10 minutes. Then place them in a mixing bowl and mash them, removing large pieces of skin.
Mash in the remaining ingredients.

4 large sweet potatoes, red skin or yellow skin
1 teaspoon ground allspice
1/2 cup coconut milk
1/3 cup olive oil
2 pinches sea salt
optional: ground black pepper to taste
