Ingredient of cake with a feathery layer (3)
I believe the answer is:
egg
This clue might be a double definition.
'ingredient of cake' is the first definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'feathery layer' is the second definition.
The answer and definition can be both animals as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'with a' is the link.
Can you help me to learn more?
(Other definitions for egg that I've seen before include "One beaten by a whisker perhaps" , "Rasher to go with this" , "Cooked breakfast staple" , "Poultry product" , "Reproductive cell" .)
