Grate the potatoes, and squeeze out as much of the liquids from the potato as possible.
Add the grated celery, flour, hing, chives, egg, and fold to mix. Add salt and pepper to taste.
Place a pan on the stove over medium heat. Once the pan is hot, melt your butter.
Place a palm-sized amount of the potato mixture into the pan and shape it into a pancake. Cook for 3-4 minutes on each side until they are crispy and golden brown.
Remove from heat and place on a paper towel-lined plate to absorb excess grease. Repeat the previous step with the remaining potato mixture.
Top with a sprinkle of sour cream and fresh parsley, or serve with your favorite dipping sauce, and enjoy!
