Combine the ingredients

• Add the milk, condensed milk, coffee and chopped chocolate to a pot.

Melt the chocolate

• Warm over very low heat, whisking every few minutes, until the chocolate is fully melted.

Simmer and reduce

• Bring to a gentle simmer and let it go, stirring the sides and bottom with a rubber spatula every so often.
• The water in the milk and coffee evaporates, thickening the cocoa without any starches and concentrating the flavor.

Finish with salt

• Stir in a pinch of salt.

Serve

• Serve hot topped with whipped cream, cinnamon, cocoa powder and nutmeg.

Reheat (optional)

• Add to a pot and warm slowly, adding a touch of milk if it is very thick.
