Pacific edition has frozen interior (4)
I believe the answer is:
iced
'frozen interior' is the definition.
'iced' can be an answer for 'frozen' (I've seen this before). I'm unsure of the 'interior' bit.
'pacific edition has' is the wordplay.
'has' says the answer is hidden in the clue.
'ICED' is hidden within 'pacific edition'.
Can you help me to learn more?
(Other definitions for iced that I've seen before include "Chilled; decorated" , "not at all hot" , "Dressed in a sweet coat" , "Finished off cake" , "Took out" .)
