1. Combine grated vegetables in bowl. Add beaten eggs, stir to combine, then stir in flour/matzah and salt and pepper to taste. Preheat oven to 300°F, and set cooling rack on sheet pan.
2. Heat 1 1/2 tablespoons olive oil in large skillet over medium heat. When oil is hot, scoop 1/3 cup of the latke mixture into the skillet, and flatten to 1/4 inch thick. Scoop 3 more latkes into skillet. Cook 4 latkes until golden brown, about 4-6 minutes per side. Remove the latkes to cooling rack on sheet pan, and place in oven to keep warm while you cook remaining four.
3. Add another 1 1/2 tablespoons oil to skillet and cook remaining latkes. When latkes are done, serve warm with a dollop of sour cream or creme fraiche and a sprinkling of chives or scallions.
