Add all ingredients except cheese to a pot, or a Colombian olleta, and bring to a boil over high heat.

Reduce heat to medium when it boils and becomes frothy. You may need to lift the pot off the burner if it threatens to pour over the edge. Make sure to watch the pot!

Use a wooden spoon, or a traditional molinillo, to mix chocolate by rolling it between your hands.

Allow to boil and then cool by lifting off burner. Traditionally, this boiling process is supposed to make the cocoa more digestible.

Cut cheese into 1cm cubes and divide evenly into four mugs.

Pour hot chocolate into the four mugs and serve immediately with a spoon.
