Flakier bits in the middle of a piece (5)
I believe the answer is:
alike
'of a piece' is the definition.
(I've seen this in another clue)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for alike that I've seen before include "Resembling each other" , "Undistinguished" , "Akin" , "possessing similar characteristics" , "uniform" .)
