From the page: "The base to all truffles is ganache窶"a thick chocolate made by mixing heavy cream into melted chocolate which sometimes incorporates melted butter.
Homemade chocolate truffles are surprisingly easy to make, and can be very impressive as a gift.
To make truffles, all you need is 10 ounces of good-quality chocolate窶"65-70% cocoa solids will make a dark, rich candy, 10 ounces of heavy cream, and a half stick of butter.
Chop the chocolate, then heat the cream and butter in a pot until the butter is melted and the cream is just shy of boiling. Remove the cream and butter mixture from the heat, then pour it over the chopped chocolate. Mix everything together until it's smooth, then add any flavor you like窶"extracts are good, as are essential oils and alcohols (like bourbon, for example, or a flavored schnapps), but remember that a little bit goes a long way. Start with a small amount (a half teaspoon at a time) and build until the flavor is what you want it to be.
Chill the mixture for a few hours, then using a melon baller or your hands (we suggest wearing rubber gloves if you use your hands to avoid getting covered in melted chocolate), roll the chocolate into balls. You can roll the truffles in toppings like chopped nuts, shredded coconut, cocoa powder or confectioner's sugar, or sprinkles. In an airtight container, the truffles will last about 5 days, but you can freeze them for about a month.
This Valentine's Day, take a little extra time and make the effort to make your sweetheart some candy that doesn't need a velvet box to be impressive."
