Tea, but I would say that because I'm English. Fact: in England it is actually against the law not to drink tea. Also coffee and hot Ribena. Sounds weird if you haven't had it but its really good
Hawt chocolate. Made without water, so it's really milky like it's meant to be. Covered in cream and with a flake if possible. (It can also sometimes be nice with a little spoon of coffee, turning it into a mocha... because I don't like coffee much otherwise. Though coffee-flavoured things are okay.)
What's your favourite hot beverage and why? Explain yourself
