Pastila is a traditional Russian confectionery made primarily from fruit puree, sugar, and egg whites. It has a soft, chewy texture and is often flavored with natural ingredients like berries or apples. The process of making pastila involves cooking the fruit puree until it thickens, then mixing it with sugar and egg whites before drying it into a firm, yet tender, treat. Originating in the 15th century, pastila was initially created in the city of Kolomna, near Moscow. It was a popular way to preserve fruit and was enjoyed by both common people and nobility. Today, pastila remains a beloved snack in Russia and is often enjoyed with tea or coffee.
