Peka is a traditional cooking method originating from the Polynesian islands, particularly popular in Hawaii. It involves wrapping food, often meat and vegetables, in banana leaves and cooking it in an underground oven called an imu. This method infuses the food with unique flavors and moisture, making it tender and delicious. The process of preparing a peka typically includes digging a pit, heating stones, and layering the wrapped food before covering it with earth to trap the heat. Peka is often used for special occasions and gatherings, showcasing the cultural significance of communal meals in Polynesian traditions.
