Bishop on course that's short and sweet (8)
I believe the answer is:
syllabub
'sweet' is the definition.
(I know that syllabub is a type of sweet)
I can't explain the remainder of the clue.
(Other definitions for syllabub that I've seen before include "last part of meal?" , "Sweet creamy dessert" , "Alcohol-laced dessert" , "Buy balls (anag) - sweet" , "Cream dish" .)
