Grass, I recall, not half-cut (10)
I believe the answer is:
citronella
'grass' is the definition.
(citronella is a type of grass)
'i recall not half-cut' is the wordplay.
'half-cut' indicates an anagram (half-cut can mean drunk).
'i'+'recall'+'not'='irecallnot'
'irecallnot' with letters rearranged gives 'CITRONELLA'.
(Other definitions for citronella that I've seen before include "Insect-repelling oil" , "South Asian grass" .)
