Channel showing one filling pastries after a turnover? (6)
I believe the answer is:
strait
'channel' is the definition.
(strait is a kind of channel)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for strait that I've seen before include "Narrow strip of water between two larger ones" , "Narrow channel of the sea joining two larger bodies of water" , "Narrow sea-channel" , "Catch in a trap" , "Narrow or difficult" .)
