Add the chocolate to the Thermomix bowl and grate for 5 sec/speed 9. Scrape down the sides of the bowl with a spatula.
Add the milk and heat for 4 min/80°C/speed 2 with the measuring cup on.
Froth the hot chocolate for 30 sec/speed 9, increasing the speed gradually.
Enjoy whilst it's hot. If doubling or tripling the recipe, you may need to increase the heating time by a minute or two.
Notes
Chocolate: I love dark chocolate, but you could use any chocolate. Milk chocolate is sweet for this recipe, so you might want to reduce the amount added.Milk: Any milk can be used for this recipe. I love to use half cow's milk and half almond milk.
