The Rabbit in Chocolate sounds amazing...
Seems the Aztecs and the Mayans combined the hot fire of chilis/spicy cinnamon with the richness of chocolate in their templar drink...similar to our modern day hot chocolate:
Basic:
Boil a litre of milk (or water, like in the ancient Mexican style)
When the milk is warm (not hot) add a chocolate tablet; broken into pieces
Stir with a blender (but be careful! the blender's electric cord should NOT touch the pot or any other hot thing around it)
When the chocolate has dissolved add ½ - ¾ cups of sugar (depending how sweet you like your chocolate) and blend in fast; make sure the sugar is completely dissolved in the chocolate otherwise it will be bitter no matter how much sugar you may add afterwards
Add a teaspoon of cinnamon or natural vanilla flavour (artificial vanilla flavour with chocolate results in an awful medicine like flavour) if you like, and blend again
Let the mixture boil, when it starts to get bubbly quickly remove the pan from the stove top, and rest the bottom against a soaked cloth
Put again on stove top, it should get bubbly almost immediately, remove once again and repeat one last time. This aerates the chocolate which enhances the flavour.
In a mug, put about 1/2-3/4 of the chocolate mixture, and add cold milk, until the temperature and/or the concentration of the flavour is right for your tastes
Accompany with French/Danish pastries and enjoy!
Mayan "xocoatl" :
Add the crude powder or the chocolate tablets (broken down in a pestle and mortar) and add to cold water
Bring to a boil over a medium heat while stirring
The Mayans were said to have added local herbs also; but what they might have been as far as I know as been lost in antiquity and no doubt no longer exist!?
Aztec "Cacahuatl" :
Add the cocoa powder to a non-reactive pan and add to cold water (the Aztecs are said to have refined the Mayan "xocoatl", by grinding the powder finer than the Mayans)
Add some chilli water (chop chillies and soak in boiling water to make a 'tea'), vanilla beans/pods and honey
Let the mixture boil while stirring constantly, when it starts to get bubbly quickly remove the pan from the stove top and allow to cool slightly
Place back on the flame and continue to stir to the boil again
Repeat the cooling and re-boiling
Repeat again: this aerates the chocolate which enhances the flavour
Chef notes
You should now have a drink similar to the Aztec drink, which should be: finely ground, soft, foamy, reddish, bitter and spicy No amounts are given, as it is very much a case of producing them to suit your individual taste...Bon appetite and enjoy!
