Casaba or cantaloupe (5)
I believe the answer is:
melon
This clue is a double definition.
'casaba' is the first definition.
(I've seen this in another clue)
'cantaloupe' is the second definition.
(I've seen this in another clue)
(Other definitions for melon that I've seen before include "Killing" , "US profits" , "Gourdlike fruit" , "Eg, cantaloupe, galia" , "Sweet juicy fruit" .)
