Beat and stirred broth (5)
I believe the answer is:
throb
'beat' is the definition.
(throb is a kind of beat)
'stirred broth' is the wordplay.
'stirred' indicates anagramming the letters.
'broth' with letters rearranged gives 'THROB'.
'and' acts as a link.
(Other definitions for throb that I've seen before include "Sound of engines" , "Broth (anag.)" , "Have strong or irregular heartbeat" , "Beat rhythmically" , "Strong rhythmic beat" .)
