Ratatouille or bouillabaisse (4)
I believe the answer is:
stew
This clue is a double definition.
'ratatouille' is the first definition.
(I've seen this in another clue)
'bouillabaisse' is the second definition.
(I've seen this in another clue)
(Other definitions for stew that I've seen before include "Artificial oyster bed" , "Tight spot" , "hotpot" , "State of anxiety; dish" , "Cook by long slow simmering" .)
