Afford to cook pears (5)
I believe the answer is:
spare
'afford' is the definition.
(synonyms)
'cook pears' is the wordplay.
'cook' indicates anagramming the letters.
'pears' anagrammed gives 'SPARE'.
'to' acts as a link.
(Other definitions for spare that I've seen before include "not in actual use" , "Excess to requirements" , "This tyre around the middle is fat" , "Extra; lean" , "Surplus to requirements" .)
