Limb almost entirely covered in cooked food served at breakfast (9)
I believe the answer is:
marmalade
'food served at breakfast' is the definition.
I can't tell whether this defines the answer.
'limb almost entirely covered in cooked' is the wordplay.
'limb' becomes 'arm' (arm is a kind of limb).
'almost' means to remove the last letter (most of the word but not all of it).
'entirely' becomes 'all' (I've seen this before).
'covered in' indicates putting letters inside.
'cooked' becomes 'made' ('make' can be a synonym of 'cook').
'all' with its final letter removed is 'al'.
'arm'+'al'='armal'
'armal' going within 'made' is 'MARMALADE'.
Can you help me to learn more?
(Other definitions for marmalade that I've seen before include "Orange conserve" , "Sweet food" , "Spread" , "Breakfast preserve" , "Preserve made with citrus fruits" .)
