These are classic Ukrainian potato pancakes also called deruny. Serve for breakfast, as an appetizer or side dish. Always serve with sour cream. An easy recipe that takes around 30 minutes for the whole process!
Peel 4 large Yukon potatoes and 1 small yellow onion. Line a sieve with a large bowl so that potatoes will drain while you finish grating. Into a sieve, grate potatoes and onion onto the star-shaped hole on grater, taking turns. Onion juice will prevent potatoes from browning. Dispose most of the potato juice from bowl underneath the sieve, but do not wash the potato starch. Keep the potato starch and add the grated potatoes and onions to the bowl with starch.
Add 3 tbsp all-purpose flour, 1 egg, 1 tsp fine salt and 1/4 tsp baking soda into the potato mixture. Mix well until incorporated. Potato batter will be thick, but still liquid enough to spoon.
Heat 2-3 tbsp of grapeseed oil in a large nonstick skillet over medium heat. Spoon 1 heaping tablespoon of potato mixture to make pancakes, about 1” apart. Fry on each side until golden brown (about 3-4 mins each side). Repeat the same procedure for the remaining batter. Serve deruny warm with a dollop of sour cream.
