Only OK or absolutely perfect (4,5)

I believe the answer is:

just right

I'm a little stuck... Click here to teach me more about this clue!

'absolutely perfect' is the definition.
'just right' can be an answer for 'perfect' (I've seen this before). I am unsure of the 'absolutely' bit.

'only ok' is the wordplay.
'only' becomes 'just' (synonyms).
'ok' becomes 'right' (I've seen this before).
'just'+'right'='JUST RIGHT'

'or' acts as a link.

Can you help me to learn more?

(Other definitions for just right that I've seen before include "Perfect" , "Exactly what was required" .)

I've seen this clue in the Evening Standard.
