Form of food it's possible to bake, note (5)
I believe the answer is:
kebab
'form of food' is the definition.
'kebab' can be an answer for 'food' (kebab is a kind of food). I am not certain of the 'form of' bit.
'possible to bake note' is the wordplay.
I cannot really understand how this works, but
an anagram of 'bake' is 'keba' which is present in the answer.
'note' could be 'b' (musical note) and 'b' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'it's' acts as a link.
Can you help me to learn more?
(Other definitions for kebab that I've seen before include "Shish dish" , "Meat grilled on skewer" , "Fast food" , "Post-pub snack?" , "Food grilled on a skewer" .)
