Chocolate molds are tools used to shape melted chocolate into various designs and forms. They come in different materials, such as silicone, plastic, or metal, and can create shapes like bars, truffles, or themed figures. Molds are essential for making decorative chocolates for special occasions or gifts. To use a chocolate mold, melted chocolate is poured into the cavities and allowed to cool and harden. Once set, the chocolate can be easily removed from the mold, retaining the desired shape. This process allows for creativity in chocolate-making, making it a popular choice for both home bakers and professional chocolatiers.
