After cutting back, champion swallows a liqueur (8)
I believe the answer is:
advocaat
'liqueur' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for advocaat that I've seen before include "Liqueur made from eggs, sugar and brandy" , "Liqueur made with raw eggs" , "Egg-based liqueur" , "Liqueur (for lawyers?)" , "Egg and rum drink" .)
