Drink that goes snappily with a biscuit (6)
I believe the answer is:
brandy
'drink' is the definition.
(brandy is a kind of drink)
'goes snappily with a biscuit' is the wordplay.
I cannot quite understand how this works, but
'with' could be 'and' and 'and' is found within the answer.
This explanation may well be incorrect...
'that' is the link.
Can you help me to learn more?
(Other definitions for brandy that I've seen before include "Hero's drink of choice?" , "Distilled alcohol" , "See 20" , "Strong liquor" , "Eau de vie" .)
