Came to to find a pan starting to evaporate (5)
I believe the answer is:
awoke
'came to' is the definition.
(to come to is to awake from sleep or a faint)
'a pan starting to evaporate' is the wordplay.
'pan' becomes 'wok' (wok is a kind of pan).
'starting to' indicates taking the first letters.
The first letter of 'evaporate' is 'e'.
'a'+'wok'+'e'='AWOKE'
'to find' acts as a link.
(Other definitions for awoke that I've seen before include "Roused from sleep" , "Became active again" , "Stirred" , "raised" , "Came round" .)
