Heat milk and add the chocolate flakes, and 1 tsp spice mix. Stir or whisk until fully dissolved.
Add orange zest, and stir or whisk again. Alternatively, place all ingredients into a chocolate shaker, and heat in the microwave for 1
-2 minutes without the lid. Remove from the microwave, add the lid and shake for 10-15 seconds, until all ingredients are fully blended.
Pour into a hot chocolate mug, and serve immediately.
