How to make the best Ukrainian potatoes pancakes

Ingredients for deruny:
5 medium-size potatoes (about 1.5 lb)
1 onion
1 egg
3 Tbsp of all-purpose flour
1 Tbsp of sour cream
1 tsp of salt and pepper to taste
oil (for frying)

How to Make Deruny:

1. Prep all the ingredients. Peel potatoes and onion.
Take a big bowl, grate potatoes and onion (on the star-shaped grater), taking turns and mixing the grated mixture. Onion juice will keep potatoes from browning.
3. Add flour, egg, and sour cream and mix it well, then add 1tsp salt and some black pepper batterer should still be liquid enough so you can quickly scoop it.
4 . Warm up a skillet with 2-3 Tbsp of oil over medium/high heat. Add 1 heaping Tbsp of the mixture at a time to the skillet fry on one side until golden brown in color, then flip to the other side and fry for the same amount of time. Repeat the same procedure for the rest of the batter.
5. Serve deruny warm, they are best with sour cream, enjoy.
