Vegetable that becomes gooey when cooked
I believe the answer is:
okra
'vegetable that becomes gooey when cooked' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for okra that I've seen before include "vegetable soup ingredient" , "old ladies' fingers" , "Long green tropical vegetable" , "Lady's fingers; gumbo; bhindi" , "Bhindi in Ind. cookery" .)
