Cook tangy pie– like mummy? (8)
I believe the answer is:
egyptian
'mummy?' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for egyptian that I've seen before include "Nationality of citizen of Cairo" , "Cleopatra or Tutankhamun, say" , "Nationality of Cleopatra" , "NE African" , "One from Suez" .)
