I got some chocolate biscuits today, but when I opened them they were all melted, even indoors with A/C on. So I put them in the fridge which solved the problem but now they are stuck together in a biscuit loaf. I had to cut it up with a bread knife, but it doesn't taste right now. McVities really needs to look in to a different "export" recipe with higher melting point IMO, for use outside of temperate climate zones.
