Stir your ground cinnamon and cacao powder into a tablespoon or two worth of boiling hot water in your pan first.
Then add everything else, pop the heat on medium, stir a couple of times and eagerly await your comfort in about 3 minutes time! As soon as you see a simmer, you’re ready. Do not boil it.
THERMOMIX NOTE: You could make your almond milk (3 cups water to 1.5 cups almonds) and pour all out of bowl. Rinse any mealy bits of nut out of the bowl. Strain milk back in and heat everything all together for 3-4 minutes, speed 2 on 100C temp.
