Seagull soars off dropping small greasy morsel (7,4)
I believe the answer is:
sausage roll
'morsel' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps there's an association between them I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for sausage roll that I've seen before include "Pork and pastry snack" , "Bit of food" , "Minced meat in pastry snack" , "Savoury of minced meat wrapped in pastry" , "Cylindrical snack" .)
