Sour cream and chives or applesaucefor serving (optional)
Instructions
Grate the potatoes and onion halves on the large holes of a box grater.
Gather the grated potatoes and onion in a kitchen towel or cheesecloth and twist both ends to squeeze out as much water as possible. There will be lots!
Combine the grated potato and onion, egg, flour, baking powder, salt, and pepper in a large bowl and mix well.
Heat a large outdoor griddle (Blackstone) to medium high. Pour enough oil on the surface to coat it with a thin layer of oil. You can use a silicone brush to spread it evenly over the surface.
Drop scoops (2 to 3 tablespoons) of batter onto the griddle and press lightly with the back of a spatula to flatten them to about ¼-inch thick.
Cook until golden brown on the bottom, about 5 minutes. Flip the patties, adding more oil if needed and cook until the other side is golden brown, about 5 minutes more.
Transfer to paper towels to drain and serve warm with sour cream and chives or applesauce, if desired.
Notes
Work quickly--Assemble and cook your latkes as quickly as possible after grating the potato as it will begin to discolor quickly.
Squeeze, squeeze, squeeze--Take time to really squeeze as much liquid as you can out of your potato mixture. Wet potato cakes will fall apart!
Keep it level--Make sure that your outdoor griddle is level so that the oil evenly coats the surface.
Dietary--This recipe is suitable for dairy-free and vegetarian diets.
