Troubled destination for the stock (2,3,4)
I believe the answer is:
in the soup
'stock' is the definition.
Both the answer and definition are adjectives.
Perhaps they are linked in a way I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for in the soup that I've seen before include "having problems" , "Experiencing serious difficulties" , "Position of stock" , "Where noodles might be" , "Suffering difficulties" .)
