Fine cook, Betty I fancy (7-3)

I believe the answer is:

tickety-boo

'fine' is the definition.
(I've seen this before)

'cook betty i fancy' is the subsidiary indication.
'fancy' indicates an anagram.
'cook'+'betty'+'i'='cookbettyi'
'cookbettyi' is an anagram of 'ticketyboo'.

(Another definition for tickety-boo that I've seen is " Fine".)

I've seen this clue in The Telegraph.
