Food a blockhead gets to bake badly (5)
I believe the answer is:
kebab
'food' is the definition.
(kebab is a kind of food)
'a blockhead gets to bake badly' is the wordplay.
'a blockhead' becomes 'b' (head letter of 'block').
'gets' says to put letters next to each other.
'badly' indicates anagramming the letters.
'b'+'bake'='bbake'
'bbake' with letters rearranged gives 'KEBAB'.
(Other definitions for kebab that I've seen before include "Small pieces of meat and vegetables cooked on skewer" , "Meat preparation" , "Fast food" , "Turkish meat dish" , "Meat and/or vegetables cooked on skewer" .)
