Woman starts with pork and mince (3)
I believe the answer is:
pam
'woman' is the definition.
'starts with pork and mince' is the wordplay.
'starts with' suggests taking the first letters.
The initial letters of 'pork and mince' is 'PAM'.
(Other definitions for pam that I've seen before include "Female" , "- Ayres, English poet" , "Short girl's name" .)
