Step 1

Peel the potatoes and onion, then rinse with cold water.

Step 2

In a large bowl, grate potatoes and onion on the star-shaped side of a grater, taking turns and mixing the grated mixture. This will prevent potatoes from browning.

Step 3

Add eggs, flour, salt, and pepper and mix well. The batter will be on a liquid side. Alternatively, you can prepare it in a food processor by grinding all ingredients together until no large chunks are left, for about 3-4 minutes.

Step 4

Preheat a large non-stick skillet on medium-high heat and add 1 tbsp of oil. Add a large spoonful of pancake batter and fry until golden brown, flip and cook on the other side. Repeat with the remaining batter.

Step 5

Serve the deruny hot with a dollop of sour cream. Makes about 30 deruny.
