A recipe is merely words on paper; a guideline, a starting point from which to improvise. It cannot pretend to replace the practiced hand and telling glance of a watchful cook. For that reason feel free to stir your own ideas into this dish. When you cook it once, it becomes yours, so personalize it a bit. Add more of an ingredient you like or less of something you don't like. Try substituting one ingredient for another. Remember words have no flavour; you have to add your own!
2. Bake the sweet potatoes until tender, about 30 minutes.
3. Cut the tops off of the sweet potatoes and scoop the flesh into a bowl, leaving it about 1/2 inch thick inside the potatoes. Add the raisins, ginger and butter to the sweet potato. Season with salt and mash together. Scoop back into the reserved potato skins and bake until golden, about 20 minutes.
