For those who don't know, dishwasher vodka involves drinking removing a quarter of the vodka from a bottle, refilling the bottle with crushed boiled sweets of your choice, doing the lid up tight and putting it through a 70 degree hot dishwasher cycle to cook the sweets into the vodka. It's delicious.
The bit I can't figure out is how best to crush the sweets and get them in the bottle. I've been leaving them in their wrappers and whacking them with a hammer on a chopping board, but they cut through the wrappers and even two plastic bags, leaving a sticky mess everywhere.
Is there a better way?
