Why does heat from the microwave make bread floppy while heat from a toaster makes bread crispy?

894 viewsOtherTechnology

I made a toaster waffle for myself this morning. Growing impatient, I popped it out before it was all the way done. As I was buttering it, I noticed parts of the waffle were still cold. Since there was already butter and syrup on it, I couldn’t put it back in the toaster. I threw it in the microwave for 20 seconds and it came out floppy instead of crispy. What gives?

Because a microwave does not generate heat. It generates a specific kind of electromagnetic wave that is really good at exciting (i.e. making hot) water and fat molecules.

So, really what you are asking is “why is my steamed bread floppy, but my dried burnt bread crispy”. Which should be kinda self explanatory.
