Cakes and fruit I'd served up in a sorry state (10)
I believe the answer is:
distressed
'cakes and fruit' is the definition.
I can't tell whether this defines the answer.
'i'd served up in a sorry state' is the wordplay.
'served up' is a reversal indicator (in a down clue, going upwards).
'in a sorry state' becomes 'stressed' (I can't justify this - if you can you should believe this answer much more).
'id' written backwards gives 'di'.
'di'+'stressed'='DISTRESSED'
Can you help me to learn more?
(Other definitions for distressed that I've seen before include "like Samson when deprived of his strength?" , "in anguish?" , "In deep pain or sorrow" , "Upset; deliberately aged" , "Anxious" .)
