Meanwhile, in medium bowl, beat butter, corn syrup, chocolate and half-and-half with electric mixer on medium speed until smooth. Stir in powdered sugar. Mixture will seem dry and crumbly. Turn fondant out onto work surface; knead until smooth. Divide fondant into 24 pieces. Shape each piece into ball. Flatten each ball slightly; mold around drained cherry, covering cherry completely. Refrigerate at least 1 hour or until very cold and firm.
