Put Charles in iron-burning dish (6)
I believe the answer is:
flambe
'dish' is the definition.
Both the definition and answer are verbs in their base form.
Maybe you can see a link between them that I can't see?
'put charles in iron-burning' is the wordplay.
'put' is an insertion indicator.
'charles in iron' becomes 'b' (I am not sure about this - if you are sure you should believe this answer much more).
'burning' becomes 'flame' (flame is a kind of burning).
'b' placed into 'flame' is 'FLAMBE'.
Can you help me to learn more?
(Other definitions for flambe that I've seen before include "Of food, sprinkled with alcohol and set alight" , "(Of food) served in alcohol and set alight" , "(Of food) served with burning spirits" , "Pour liquor over a dish and ignite" , "dish on fire" .)
