Pounds of British food (5)
I believe the answer is:
beats
'pounds' is the definition.
('beat' can be a synonym of 'pound')
'british food' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'food' becomes 'eats' (eats is a kind of food).
'b'+'eats'='BEATS'
'of' is the link.
(Other definitions for beats that I've seen before include "Buffets" , "Rhythms" , "Tans" , "Regular routes for policemen" .)
