Preparation:
Place potato chunks and garlic in a saucepan with 1 teaspoon kosher salt and water to cover. Top with a lid and simmer for 15 to 20 minutes, or until tender. Add leeks and cook an additional 3 minutes.
Remove vegetables from heat, drain, and coarsely mash. Let rest for 5 minutes to cool slightly. Stir in eggs, bread crumbs, Parmesan cheese, 1 teaspoon kosher salt, and pepper. Let cool to room temperature, then chill for 1 hour.
Shape chilled mixture into 18 patties.
Heat oil in a large skillet. Cook fritters in batches for 2 to 3 minutes on each side until golden brown.
Serve hot with optional sour cream.
Yield: 18 patties or about 6 servings
