Cooking fish after commotion in front of guest (4,6)
I believe the answer is:
'cooking' is the definition.
(type of cooking)
'fish after commotion in front of guest' is the wordplay.
'fish' becomes 'fry' (I've seen this before).
'after' means one lot of letters go next to another.
'commotion' becomes 'stir' (stir is a kind of commotion).
'in front of guest' becomes 'ing' (I can't justify this - if you can you should believe this answer much more).
'fry' after 'stir' is 'stirfry'.
Can you help me to learn more?
