Drink that’s good found in New England area? (5)
I believe the answer is:
negus
'drink' is the definition.
(negus is a kind of drink)
'good found in new england area?' is the wordplay.
'good' becomes 'g' (abbreviation).
'found in' means one lot of letters goes inside another.
'new' becomes 'n'.
'england' becomes 'e'.
'area?' becomes 'us' (I am not sure about this - if you are sure you should believe this answer much more).
'n'+'e'+'us'='neus'
'g' inserted within 'neus' is 'NEGUS'.
'that's' acts as a link.
(Other definitions for negus that I've seen before include "Hot spiced port with lemon" , "Hot fortified drink" , "Abyssinian king - spiced drink" , "Ethiopian emperor (hist.)" , "Hot wine" .)
