Burger King does not typically microwave their burgers.
Burger King is a fast-food chain known for its flame-grilled burgers. They use grills with open flames to cook their burgers, giving them a distinct smoky flavor and grill marks. However, keep in mind that practices and cooking methods can vary between different locations, and restaurants may occasionally use different cooking techniques to accommodate high customer demand or other factors.
If you have any specific concerns or questions about Burger King's food preparation methods, I recommend reaching out to the restaurant directly or checking for updates on their official website or social media channels.
