The basic ingredients of any chocolate truffle are flavoring, liquid, and chocolate―which is called 'ganache'. For the longest time, this confectionery treat was only available to the rich and the affluent. Today they are available anywhere and everywhere―chocolate shops, candy stores, and even supermarkets. Truffles come in a wide range of flavors, right from dark, milk, and white chocolate to the fruit-flavored variety. They come in a liqueur flavors as well, like Kahlua and Frangelico.
