Ingredient served up in yakimono dumplings? (4)
I believe the answer is:
udon
'ingredient' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'up in yakimono dumplings?' is the wordplay.
'up' says the letters should be written in reverse (in down clue: letters go upwards).
'in' indicates the answer is hidden within the clue.
'nodu' is hidden in the letters of 'yakimono dumplings'.
'nodu' back-to-front is 'UDON'.
'served' is the link.
Can you help me to learn more?
(Another definition for udon that I've seen is " noodle, thick".)
