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 before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for trouble that I've seen before include "'Care, distress (7)'" , "that follow witches' toil?" , "Disturb; difficulty" , "Strife, difficulty" , "Difficulty; public disorder" .)
