As a food and a flavoring, chocolate is widely popular.people everywhere enjoy chocolate candies, pastries, and drinks. Chocolate is made from the seeds, or "beans," of the tropical cacao tree. The beans grow inside leathery pods that are found both on the trunk and on the branches of the tree. Workers cut the pods from the tree trunks with large heavy knives called machetes and from the branches with long-handled knives. The purple or creamy-white beans are shelled from the pod, which is about the size of a small cucumber.   At this stage the bean has a raw bitter taste. As the first step in the long process of making appetizing chocolate, the beans are piled in bins for several days. Bacterial action causes them to take on a rich brown color and the fragrance of chocolate. After several more days they become dry enough to prevent spoilage, and they are bagged for shipment.   When they arrive at the factory, the beans are roasted in large rotating machines. This improves the flavor still more and dries the shells of the beans so that they can be easily removed in the next machine, the "cracker and fanner." Here the beans are cracked, and fans blow away the brittle shells, leaving the nibs, or meat. The nibs are the part used for making chocolate products. The shells are saved for use in fertilizer or as feed for cattle.   About 50 percent of the nibs is made up of a fatty substance known as cocoa butter. In the next stage large grinding stones or heavy steel disks crush the nibs, creating frictional heat that melts the butter. The hard parts of the nibs are ground to powder. The result is a smooth, dark-brown liquid known as chocolate liquor. When poured into molds, the liquid hardens into cakes of unsweetened chocolate, which are used in cooking. To produce cocoa powder the warm liquor is pumped into a filter press. Pressure exerted by a pump forces much of the cocoa butter, a yellow liquid, through the pores of a strong filter cloth. The filter cloth holds back a light brown cake of solid particles, which is then ground and sifted to form cocoa powder.   Chocolate for eating is made by adding cocoa butter to chocolate liquor. For sweet, or dark, chocolate finely powdered sugar is added. For milk chocolate a third ingredient, milk, is included. Various flavorings may also be added. These mixtures go through a set of rollers that reduces them to a paste.   Next, more machines with heavy rollers knead the chocolate mass for periods ranging from a few hours to several days. This process, called conching, makes the rather gritty mixture very smooth. Varying the temperature in the machines and the movement of the rollers produces variations in flavor.   Finally the chocolate is tempered, or heated to a high temperature. This reduces the size of large fat crystals and gives the chocolate a velvety quality. The chocolate is poured into molds by automatic machinery (see Candy).   Cocoa butter is sold separately for other purposes. When solid, it is white and pleasant tasting. Baking firms may use it instead of regular butter. well..i believe its too enough for a series to start...next time
