Roasting is a cooking technique that involves exposing food to dry heat in an oven or over an open flame. This method is commonly used for meats, vegetables, and nuts, resulting in a rich, caramelized exterior while retaining moisture and flavor inside. The high temperatures used in roasting encourage browning through the Maillard reaction, enhancing the dish's overall taste and aroma. It's a versatile technique that can be applied to various ingredients, making it a popular choice for both everyday meals and special occasions.
