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

'some coffee' is the definition.
(instant coffee)

I cannot understand how the rest of the clue works.

(Other definitions for instant that I've seen before include "Tick" , "Sudden; moment" , "like some coffee?" , "This coffee is made from powder" , "Fast, flash" .)

I've seen this clue in The Mirror.
