Nutritious and fragrant, coffee and chocolate drink with citrus notes. Especially nice to drink a cup on a cold day.
Pour milk into a saucepan, add chocolate broken into small pieces, zest, coffee and nutmeg. Heat until chocolate melts. Increase heat and, stirring constantly, bring to a boil. Remove from fire immediately.
Beat with a whisk until foam appears. Return to heat and bring to a boil again. Remove from heat and whisk again until foamy.
Remove the orange zest from the drink. Pour into circles.
