Try as you might, there will come a point on a long road trip where the only coffee available to you is watery petrol station coffee. You could buy an energy drink, or you could mix in a hot chocolate packet for something that actually tastes okay.

Will it transform crappy coffee into a third wave latte? No. But it will turn your coffee-scented water into caffeinated, coffee-scented hot chocolate, which is much more palatable. Plus, you can pack your favourite packs of cocoa, giving you just a little more control over the taste of your very necessary caffeine.
