Moment for some coffee (7)
I believe the answer is:
instant
I believe this clue is a double definition.
'moment' is the first definition.
(I know that moment can be written as instant)
'some coffee' is the second definition.
(instant coffee)
'for' is the link.
(Other definitions for instant that I've seen before include "Tick" , "No need to cook" , "Short time; immediate" , "pressing" , "Moment - this month" .)
