A pot of water sits on my stove from early October to late December.
I just turn on the stove, let the flames heat up the water, take my favorite mug and fill it with hot water and chocolate powder and voila! Hot chocolate!
Usually we heat up the pot of water in the morning for a cup of cocoa before school. However, I like to heat up the water at night, after everyone has gone to bed. I sit at the computer, listen to my school's lectures, and sip hot cocoa. It's the only way to do class work.
