One can make broth from this pulse (5)
I believe the answer is:
throb
'this pulse' is the definition.
(I know this)
'one can make broth' is the wordplay.
'broth' can be anagrammed to 'THROB'.
Though, I'm not sure how the anagram is indicated.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for throb that I've seen before include "Strong rhythmic beat" , "Pulsate with force" , "Beat like heart" , "Palpitate, quiver (with emotion)" , "Pulsate strongly" .)
