Kolaches are a type of pastry that originated in Central Europe, particularly in the Czech Republic. They are made from a soft, yeast-based dough that is typically filled with various sweet or savory ingredients. Common fillings include fruit preserves, cream cheese, or meats, making them versatile for breakfast or dessert. In the United States, especially in areas with a strong Czech heritage, kolaches have become popular treats. They are often enjoyed at bakeries and festivals, showcasing a variety of flavors and styles. The dough is usually slightly sweet, providing a delightful contrast to the fillings.
