Trail mix bit (6)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
raisin
'trail mix bit' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for raisin that I've seen before include "sultana, say" , "Somewhat dry fruit" , "Fruit for the Christmas cake" , "Cultivating" , "A dried grape used in cake" .)
