I make hot chocolate frequently.
I grab as many mugs as I have takers.
I put one tablespoon of cocoa powder into each mug, followed by two heaping tablespoons of ordinary white sugar.
I add one or two tablespoons of milk, and stir it into a thick paste. My favorite milk these days is carried by Safeway: Natrel Organic Homogenized milk, 3.25% milk fat. It has a nice taste.
Make sure that all the cocoa powder is fully incorporated, because little balls of cocoa powder will taste rather bitter. You can use the back of a spoon to press any renegade cocoa bits against the inside of the mug.
Add enough milk to fill the mug.
Microwave for a couple of minutes.
Remove and stir again.
Taste a spoonful.
Add more sugar.
Microwave for about 30 seconds more.
Add a small handful of mini-marshmallows for those who like them.
