A final course upbraided (7)
I believe the answer is:
dessert
'a final course' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for dessert that I've seen before include "Spotted Dick is one" , "Pudding, sweet" , "End of meal" , "Fool possibly" , "Sweet, last course of a meal" .)
