Bake off British food (5)
I believe the answer is:
kebab
'food' is the definition.
(kebab is a kind of food)
'bake off british' is the wordplay.
'off' indicates an anagram.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'bake' is an anagram of 'keba'.
'keba'+'b'='KEBAB'
(Other definitions for kebab that I've seen before include "Brochette" , "Skewered meat dish" , "Meat and/or vegetables cooked on skewer" , "Spitted and grilled meat" , "spiked food" .)
