Rugelach is a traditional Jewish pastry that originated in Eastern Europe. It consists of a rich, buttery dough that is rolled out, spread with various fillings, and then rolled into a crescent shape. Common fillings include fruit preserves, nuts, chocolate, and cinnamon sugar. These delightful treats are often served during holidays and special occasions, making them a popular choice for celebrations. Rugelach can be enjoyed warm or at room temperature and are typically dusted with powdered sugar before serving, adding a sweet finishing touch to their flaky texture.
