At sea it cooks stuff (7)
I believe the answer is:
satiate
'stuff' is the definition.
(I know that stuff can be written as satiate)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for satiate that I've seen before include "Overfill - gorge" , "Overstuff" , "Fill to satisfaction" , "content" , "Have more than enough" .)
