making chocolate is a process that has many steps. first, the cocoa beans are collected and put in piles or containers to make them ferment. fermentation makes the sugar in the beans turn into alcohol. then the beans are dried and cleaned. chocolate makers must cook the beans, and then crush them to make the cocoa butter and the chocolate liquor come out of them. then the chocolate maker mixes different ingredients together to make the different kinds of chocolate. dark or bittersweet chocolate is made from sugar, cocoa butter, and chocolate liquor. milk chocolate uses all of those ingredients plus milk and vanilla. white chocolate does not contain chocolate liquor, but only cocoa butter, along with sugar, milk and vanilla. after these ingredients are put together, the chocolate maker is still not finished. one of the last things to be done is something called conching. conching means crushing the chocolate very finely and keeping it warm so that it is liquid. before chocolate is conched, it feels very rough in the mouth instead of smooth. conches use heavy rollers that plow back and forth through the chocolate paste under regulated speeds and temperatures. conching for several hours to several days makes good chocolate. the last step in making chocolate is called tempering. the chocolate is heated, and then shaken, and then cooled a few times.
