Kopytka (literally "little hooves") are a kind of potato dumpling. They are very similar to gnocchi although they are typically served baked with cheese, fried bacon or onion. The dish is a part of Belarusian, Lithuanian and Polish cuisines.
If I had to eat only one thing for the rest of my life, it just might be this. My grandmother could make placki like no one else, but she stopped cooking years ago. I looked far and wide for a recipe that sounded like hers. Many recipes call for large shreds of potato or didn't include onion. Finally I found something I thought my work and decided to make them on Christmas morning for my family. My grandmother said it all: "Good placki!" I'm glad I can keep the tradition alive.
