Cook using British fuel (4)

Ross

I believe the answer is:

boil

'cook' is the definition.
(boiling is a kind of cooking)

'british fuel' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'fuel' becomes 'oil' (oil is a type of fuel).
'b'+'oil'='BOIL'

'using' acts as a link.

(Other definitions for boil that I've seen before include "Cook, swelling" , "Abscess" , "Sore with a hard core filled with pus" , "become inflamed" , "Cook in hot water" .)

I've seen this clue in The Sun and The Times.
