Sweet Potato Latkes

Makes about 16 latkes.1 medium yellow onion2 pounds sweet potato4 tablespoons rice flour or quinoa flour3 teaspoons kosher saltPinch cayenne2 large egg, beatenExtra Virgin Olive OilGrate the onion into a large bowl. Grate sweet potatoes into the same bowl. Wring out excess liquid by placing in a towel and squeezing the liquid. Mix the latke mixture with the flour, salt, and cayenne. Stir in the egg.Heat oil in a large cast iron (my preference) skillet over medium heat. Working in batches, spoon about 1/4 cup of the latke mixture into the skillet, pressing lightly to form 2-3-inch pancakes Do not overcrowd the pan. Cook, turning once, until just golden, about 2 minutes per side. Place in warm oven to hold.Serve the latkes topped with a small dollop of applesauce or sour cream or horseradish.Serve immediately.
