Stir meal Mrs cooked (7)
I believe the answer is:
slammer
'stir' is the definition.
(I've seen this before)
'meal mrs cooked' is the wordplay.
'cooked' is an anagram indicator (letters cooked into a new form).
'meal'+'mrs'='mealmrs'
'mealmrs' anagrammed gives 'SLAMMER'.
(Other definitions for slammer that I've seen before include "One criticising, as it were" , "cocktail?" , "Prison (slang)" , "One severely criticises" , "One pulling off lots of tricks" .)
