Early Methods in the Tropics
As the cacao bean is grown in tropical countries, it is there that we must look for the first attempts at manufacturing from it a drink or a foodstuff. The primitive method of preparation was very simple, consisting in roasting the beans in a pot or on a shovel to develop their flavour, winnowing in the wind, and then rubbing the broken shelled beans between stones until quite fine. The curious thing is that on grinding the cacao bean in the heat of a tropical day we do not produce a powder but a paste. This is because half the cacao bean consists of a fat which is liquid at 90° F., a temperature which is reached in the shade in tropical countries. This paste was then made into small rolls and put in a cool place to set. Thus was produced the primitive unsweetened drinking chocolate. This is the method, which Elizabethans, who ventured into the tangled forests of equatorial America, found in use; and this is the method they brought home to Europe. In the tropics these simple processes are followed to this day, but in Europe they have undergone many elaborations and refinements.
If the reader will look at the illustration entitled “Women grinding chocolate,” he will see how the brittle roasted bean is reduced to a paste in primitive manufacture. A stone, shaped like a rolling-pin, is being pushed to and fro over a concave slab, on which the smashed beans have already been reduced to a paste of a doughy consistency.
