Does it open the door to success in bread flavouring? (6,4)
I believe the answer is:
sesame seed
'success in bread flavouring?' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'does it open the door' is the wordplay.
I cannot really understand how this works, but
'it' could be 'sa' (old-fashioned abbreviation for sex appeal) and 'sa' is located in the answer.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for sesame seed that I've seen before include "Small oval seeds baked into the crusts of bread or on buns" , "Oil producer" .)
