Meat Kate's cooking (5)
I believe the answer is:
steak
'meat' is the definition.
(I know that steak is a type of primal cut)
'kate's cooking' is the wordplay.
'cooking' indicates anagramming the letters (cook can mean to falsify or distort).
'kates' anagrammed gives 'STEAK'.
(Other definitions for steak that I've seen before include "Takes (anag.)" , "Good beef" , "Porterhouse, perhaps?" , "Portion of meat" , "Meat (rare, medium or well done?)" .)
