Firefire tofu is a traditional cooking method, usually using bamboo tubes or iron pots. Boilers are mainly used for heating water or heating equipment and are not suitable for direct use in cooking food. Therefore, using a boiler to make wood-fired tofu may not be appropriate. It is recommended that you use traditional bamboo tubes or iron pots for cooking to ensure food safety and taste. If you don't have the right cooking equipment, consider purchasing tools specifically designed for making wood-fired tofu or enjoy the dish at a restaurant.
