'glaze' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'for one cut incorporating whiskey' is the wordplay.
'for one' becomes 'eg' (both can mean 'for example').
'cut' becomes 'gash' (a gash is a wound or cut).
'incorporating' indicates putting letters inside.
'whiskey' becomes 'W' (alpha bravo charlie delta ...).
'gash' placed around 'w' is 'gwash'.
'eg'+'gwash'='EGGWASH'
