1. Place the grated potatoes, garlic and shallot in a large bowl. Add the baking powder, paprika, cayenne, salt and pepper. Using your hands, toss until well distributed. Add the flour and eggs, mix until well combined.
2. Heat about 1/4 inch oil in a large skillet until very hot. Add the latke by 1/3 cup full, flatten with the spatula to about 1/2 inch thick; brown in the oil (adjust the heat so it takes about 3 minutes per side); then flip and cook the other side; working in batches so as not to overcrowd. (Keep latke hot in 200 degree oven on a cooling rack set on a baking sheet).
3. Prepare the topping, if using; combine all ingredients in a bowl and mix well.
4. Serve hot with a dollop of topping, if desired. Makes 4 servings
