Dried out blubber before dessert came round (7,2)

'dried' is the definition.
The answer and definition can be both related to change as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?

'blubber before dessert came round' is the wordplay.
'blubber' becomes 'sob' (I've seen this before).
'before' becomes 'ere' (poetic term for 'before').
'dessert' becomes 'pud' (short for pudding).
'came round' says the letters should be written backwards (I've seen 'coming round' mean this).
'pud' back-to-front is 'dup'.
'sob'+'ere'+'dup'='SOBERED UP'

'out' is the link.
