Peel one layer of the leek and wash well.
Cut the leek to circles.
Peel the potatoes and cut into cubes.
Put the leek and the potato in the pot.
Add water to cover by 2 cm.
Bring to a boil and cook over medium- low heat for 25 minutes until the potatoes and leek become really soft.
Drain the potatoes and leek in a colander. Let them cool a few minutes and let the water drip out.
When dried – place it into the food processor and grind it all the way until fully mashed.
Transfer to a large bowl.
Add the spices, salt and pepper and stir. Taste and adjust the seasoning. The mixture should be a little salty.
Add the flour and the egg and stir well.
Heat some oil (about half inches) in a large skillet.
When the oil is boiling – place a tablespoon of the mix into the oil – one at a time. Repeat the process until there is no place in the pan.
When the patties browned on one side - Carefully turn. Please note! patties will be soft in the center. It's OK - just flip carefully.
Fry until brown on the other side and transfer to paper towels.
If the oil level falls - add more oil.
Voila! Ready!
Can be served hot straight from the pan, it is possible to cool overnight in the refrigerator and serve cold the next day (it's even more delicious).
*Serve with sour cream.
