Cook finds form of energy in pub (5)
I believe the answer is:
baker
'cook finds form' is the definition.
'baker' can be an answer for 'cook' (type of cook). I am not sure about the 'finds form' bit.
'energy in pub' is the wordplay.
'energy' becomes 'K.E.' (K.E. is an example).
'in' indicates putting letters inside.
'pub' becomes 'bar' (both are drinking establishments).
'ke' going within 'bar' is 'BAKER'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for baker that I've seen before include "Bread producer" , "His 12 is13" , "Break (anag.)" , "one with lots of dough" , "job" .)
