Measure out the meat as mentioned (4)
I believe the answer is:
mete
'measure out' is the definition.
(thesaurus)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for mete that I've seen before include "Dole (out)" , "Apportion" , "Administer or bestow, as in small portions" , "Dish (out)" , "Allot" .)
