Public service announcement: it’s good to eat Mars bars straight from the freezer, but don’t try it with a Crunchie: freezing makes them totally brittle and they turn into dust. I ate all the dust I could scoop off my shirt, but had to sweep 50% of it off the floor.
Caramac will be fine … I’d be very careful with Turkish Delight though and only a fool would try to freeze a large bar of Dairy Milk Marvellous Creations Jelly Popping Candy. You better know yourself if you’re going to mess with that.
