Being successful in cooking properly (5,4)
I believe the answer is:
doing well
'being successful in cooking properly' is the definition.
I can't tell whether this defines the answer.
'being successful in cooking properly' is the wordplay.
I cannot quite understand how this works, but
'successful' could be 'in' (similar in meaning) and 'in' is found within the answer.
'being' could be 'dog' (dog is a kind of being) and 'dog' is present in the remaining letters.
'properly' could be 'well' and 'well' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for doing well that I've seen is " Making good progress, say patient".)
