They all look tasty. I'm quite lazy when it comes to hot drinks. I seldom have enough patience for cooking beverages. Unless it's hot chocolate for the kids.
My advice for anyone making hot chocolate, or anything chocolaty, is to use a good cocoa brand. Since many years we have used Valrhona cocoa. It has many cocoa flavors. It's as great for hot chocolate as it is for chocolate balls (is that the name?).
