Grape leaves are the foliage of the grapevine, a plant known for producing grapes used in various culinary applications, including wine and fresh eating. These leaves are typically heart-shaped and can vary in size and texture depending on the grape variety. They are often used in Mediterranean cuisine, particularly in dishes like dolmas, where they are stuffed with rice, herbs, and sometimes meat. In addition to their culinary uses, grape leaves are rich in vitamins A, C, and K, as well as antioxidants. They can be harvested in spring and early summer when they are tender and young. Grape leaves can also be preserved by pickling or freezing for later use.
