Cook requires good little sieve (7)
I believe the answer is:
griddle
'cook' is the definition.
(thesaurus)
'good little sieve' is the wordplay.
'good little' becomes 'g' (abbreviation for good).
'sieve' becomes 'riddle' (riddle is a kind of sieve).
'g'+'riddle'='GRIDDLE'
'requires' is the link.
(Other definitions for griddle that I've seen before include "Iron plate for cooking on" , "Circular iron plate used for baking" , "cooking accessory" , "Heated metal cooking surface" , "cooking utensil" .)
