Drink pineapple crushes at home (9)
I believe the answer is:
grenadine
'drink' is the definition.
(drink made from pomegranates)
'pineapple crushes at home' is the wordplay.
'pineapple' becomes 'grenade' (pineapple can informally mean a grenade).
'crushes' indicates putting letters inside.
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'grenade' going around 'in' is 'GRENADINE'.
(Other definitions for grenadine that I've seen before include "Sweet cordial" , "material" , "Pomegranate juice syrup" , "Pomegranate cordial" , "West Indian" .)
