Grape leaves are a popular ingredient in various Middle Eastern and Mediterranean cuisines. They are usually dark green in color, heart-shaped, and have a smooth, tender texture when cooked. Their size can vary widely, from about the size of your palm to much larger.

The flavor of grape leaves is quite unique; they possess a slightly tart, tangy taste that can be likened to sorrel or spinach with a citrusy twist. This distinctive taste adds depth and complexity to the dishes they are used in.

Grape leaves are often used as a wrap for a variety of fillings, like meat, rice, or grains, in dishes such as Dolmades or Warak Enab. They are typically blanched or boiled to soften them before use and can be eaten both hot or cold.

In addition to adding a magnificent flavor, grape leaves also offer various nutritional benefits. They are a great source of vitamins like vitamin A, C, and E, and are packed with antioxidants.

They are often available in jars at grocery stores in the international food aisle, either in a simple brine or packed in oil. If you have access to a vineyard or grow your own grapevine, you can also harvest and prepare them fresh. Remember to pick young leaves that are tender and bright green for the best quality.

Grape leaves can usually be found in the international or ethnic food aisle of a grocery store. Depending on the store, they may be with Middle Eastern or Mediterranean foods. They are often sold in jars. If you can't find them, ask a store employee for assistance.
