Cocoa and Chocolate
(e) Flavouring.
Art is shown not only in the choice of the cacao beans but also in the selection of spices and essences, for, whilst the fundamental flavour of a chocolate is determined by the blend of beans and the method of manufacture, the piquancy and special character are often obtained by the addition of minute quantities of flavourings. The point in the manufacture at which the flavour is added is as late as possible so as to avoid the possible loss of aroma in handling. The flavours used include cardamom, cassia, cinnamon, cloves, coriander, lemon, mace, and last but most popular of all, the vanilla pod or vanillin. Some makers use the choice spices themselves, others prefer their essential oils. Many other nutty, fragrant and aromatic substances have been used; of these we may mention almonds, coffee, musk, ambergris, gum benzoin and balsam of Peru. The English like delicately flavoured confections, whilst the Spanish follow the old custom of heavily spicing the chocolate. In ancient recipes we read of the use of white and red peppers, and the addition of hot spices was defended and even recommended on purely philosophical grounds. It was given, in the strange jargon of the Peripatetics, as a dictum that chocolate is by nature cold and dry and therefore ought to be mixed with things which are hot.
