Bear out one's been confiscated by cook (6)
I believe the answer is:
braise
'cook' is the definition.
(I know this)
'bear out one's been confiscated' is the wordplay.
I cannot really see how this works, but
'one's' could be 'is' (Roman numeral) and 'is' is found within the answer.
an anagram of 'bear' is 'brae' which is present in the left over letters.
This accounts for all the letters.
This explanation may well be incorrect...
'by' acts as a link.
Can you help me to learn more?
(Other definitions for braise that I've seen before include "Heat slowly" , "Fry and then stew (food)" , "Rabies (anag.)" , "Cook slowly with little liquid in closed container" , "Stew in a closed pan" .)
