How to Make It
Rinse and peel sweet potatoes. Shred with coarse blade of a food processor or a hand grater.
Put a 2-inch-deep 12- by 17-inch baking pan in a 475° oven. Add butter, cut into chunks. When butter melts, after about 3 minutes, add the sweet potatoes and sugar. Mix well with a wide spatula. Bake, turning the sweet potatoes occasionally with the spatula (taking care not to mash the mixture), until about half the sweet potatoes are browned and remainder are tender to bite, 50 to 60 minutes. Add the tequila and lime juice and mix well. Bake 5 minutes more.
Pour sweet potatoes into a bowl. Season to taste with salt and pepper. When serving, accompany with lime wedges to squeeze over potatoes.
