First cook chop then get your teeth into it (4)
I believe the answer is:
chew
'get your teeth into it' is the definition.
I can't judge whether this defines the answer.
'first cook chop' is the wordplay.
'first cook' becomes 'c' (hst letter of 'cook').
'chop' becomes 'hew' (to hew is to chop or cut down).
'c'+'hew'='CHEW'
'then' acts as a link.
Can you help me to learn more?
(Other definitions for chew that I've seen before include "Reflect on" , "Process food" , "Try to eat" , "champ" , "Work or grind between teeth" .)
