Drink that's a hit (5)
I believe the answer is:
punch
This clue is a double definition.
'drink' is the first definition.
(punch is an alcoholic drink)
'that's a hit' is the second definition.
(I've seen this before)
(Other definitions for punch that I've seen before include "Sock" , "striking power" , "Partner of Judy" , "Seaside puppet character" , "Poke" .)
