Maybe make of fool of Yankee that's drunk (6)
I believe the answer is:
whisky
'yankee that's drunk' is the definition.
I know that 'yankee' relates to this answer.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for whisky that I've seen before include "Grain alcohol" , "Spirit distilled from malted grain" , "reportedly available for Thin Lizzy gig?" , "Alcoholic drink" , "Scottish spirit" .)
