To make truffles, good chocolate is necessary. The most common good quality chocolates are the Valrhona and Barry Callebaut brands. Valrhona is available in "pistols". These are flat pieces of chocolates the size of a dime. They have the advantage of melting evenly. Other very good chocolates are offered in blocks, they should be roughly chopped with a knife. The fine taste of truffles is well worth the trouble and price! In truffles, alcohol is optional. You can choose cream of mint, rum, cognac, or applejack for added flavour.
