Conundrum of kitchen? (6)
I believe the answer is:
riddle
This clue might be a double definition.
'conundrum' is the first definition.
(I know that conundrum can be written as riddle)
'kitchen?' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'of' acts as a link.
Can you help me to learn more?
(Other definitions for riddle that I've seen before include "Difficult problem or coarse sieve" , "Word puzzle or coarse sieve" , "Brain-teaser and coarse sieve" , "unsolved problem" , "Make many openings" .)
