Crazy to consume English alcoholic drink (4)
I believe the answer is:
mead
'alcoholic drink' is the definition.
(I've seen this before)
'crazy to consume english' is the wordplay.
'crazy' becomes 'mad' ('mad' can be a synonym of 'crazy').
'to consume' indicates putting letters inside.
'english' becomes 'e' (abbreviation).
'mad' going around 'e' is 'MEAD'.
(Other definitions for mead that I've seen before include "Honeyed drink for dame" , "Cooked joint" , "sweet drink" , "Drink made of fermented honey and water" , "Honey-based alcoholic drink" .)
