Microwaves heat food in a different way to air fryers or conventional ovens, meaning the food retains a lot more moisture, affecting both the taste and the texture. What a microwave offers in speed, it often lets down in terms of taste. Because of this, they are ideal for quickly melting items, or heating up some leftovers, but there are often other tools, such as stoves or air fryers, that can do this just as easily, and with better results.
