Koláče or kolache (plural: kolaches) is a sweet pastry roll that is traditionally topped with plums or plum jam, cheese, or poppy seeds. Modern toppings might include fruit such as apricots, blueberries, cherries, lemon, pineapples, or raisins.
Its name is derived from the Czech word kola, meaning wheels, referring to the traditional, round shape of the pastry. The pastry originated in the 1700s in the Czech Republic, where round breads are some of the earliest ritual foods, usually symbolizing the sun and the moon.
