Might this turn out like 'Instant' you initially ordered (one to go)? (6,5)
I believe the answer is:
skinny latte
'might this turn out like instant you initially ordered one' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'go?' is the wordplay.
I cannot really see how this works, but
'go?' could be 'ski' (skiing is a kind of going) and 'ski' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for skinny latte that I've seen before include "Healthier drink" , "Low-calorie white coffee - sent any kilt (anag)" , "Milky preparation" .)
