Crockpot concoction (4)
I believe the answer is:
stew
'crockpot concoction' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for stew that I've seen before include "Cook; worry" , "State of anxiety; dish" , "Cassoulet" , "A hole, a fix" , "Become too hot" .)
