Cook this pulse to make broth (5)
I believe the answer is:
throb
'cook this pulse' is the definition.
'throb' can be an answer for 'pulse' (throb is a kind of pulse). I'm not certain of the rest of the definition.
'make broth' is the wordplay.
'make' indicates anagramming the letters.
'broth' with letters rearranged gives 'THROB'.
'to' is the link.
Can you help me to learn more?
(Other definitions for throb that I've seen before include "Drum" , "Beat strongly" , "Palpitate, quiver (with emotion)" , "Sound of engines" , "Strong regular beat" .)
