Crisp potato pancakes called latkes are part of Hanukkah celebrations. We've kept the traditional frying method (and sour cream to go with them), but refreshed the recipe by trading white potatoes and onions for sweet potatoes and scallions.
Coarsely grate sweet potatoes on the large holes of a box grater (or use a food processor fitted with a shredding blade). Transfer to a large bowl; stir in scallions, eggs, flour, 1 teaspoon coarse salt, and 1/2 teaspoon pepper.
Using a packed 1/4-cup measure of potato mixture per pancake, shape into 12 mounds. With hands, form each into a firm ball; transfer to a baking sheet. With palm, flatten balls into 3/4-inch-thick cakes.
In a large skillet, heat oil over medium until hot (see note, below). Using a metal spatula with a thin blade, carefully transfer 6 cakes to skillet; flatten to about 1/2 inch thick. Cook until golden brown, 4 to 5 minutes per side. Transfer pancakes to a paper-towel-lined plate; sprinkle with coarse salt. Repeat with remaining cakes. Serve immediately, with sour cream, if desired.
Donâ€™t rush -- put the skillet over medium heat, not high, so the pancakes cook through before browning too much. Reduce heat if they darken too quickly.
