4 lbs (2 Kg) sweet potatoes
4 tablespoons (60 mL) unsalted butter
¼ cup (60 mL) pure maple syrup
Coarse salt and ground pepper
Preheat oven to 400ºF. Pierce sweet potatoes all over with a knife. Place on middle oven rack. Bake until very tender when pierced with a knife, around 1 hour. When cool enough to handle, cut sweet potatoes in half. Then with a spoon, scoop out flesh into a food processor - you can discard the skins.
Add butter and syrup; process until smooth. Season with salt and pepper.
