The secret is in the unique way microwaves work. Conventional ovens heat up the air inside the oven first then heat up the surface of the food and then heat up the inside.

Microwaves are low energy electromagnetic waves that have so little energy they can’t trigger chemical reactions in the molecules they encounter.
