Putin's heart — and his dough in hot water (7)
I believe the answer is:
trouble
'hot water' is the definition.
(I've seen this in another clue)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for trouble that I've seen before include "Disquiet" , "Discord" , "Disturb; difficulty" , "Difficulty, care, worry" , "To make the effort" .)
