Two dozen for we nutty cooks
I believe the answer is:
twenty-four
'two dozen' is the definition.
('twenty-four' can be a synonym of 'two dozen')
'for we nutty cooks' is the wordplay.
'cooks' indicates an anagram.
'for'+'we'+'nutty'='forwenutty'
'forwenutty' anagrammed gives 'TWENTY-FOUR'.
(Other definitions for twenty-four that I've seen before include "Number of hours in a day" , "Two dozen" .)
