Recalled letter by queen and one by king bearing fruit (7)
I believe the answer is:
kumquat
'fruit' is the definition.
(kumquat is a kind of fruit)
'recalled letter by queen and one by' is the wordplay.
'recalled letter by' becomes 'kum' (I can't justify this - if you can you should believe this answer much more).
'queen' becomes 'qu' (abbreviation for queen).
'and' says to put letters next to each other.
'one by' becomes 'at'.
'kum'+'qu'+'at'='KUMQUAT'
'king bearing' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
(Other definitions for kumquat that I've seen before include "Asian citrus-like fruit" , "Small orange fruit" , "Small Chinese orange" , "Small oval citrus fruit" , "Chinese orange fruit" .)
