As cacao tree became more commonly available,people began experimenting with new ways of using it. Chocolate began to appear in cakes and other foods. But it wasn't until 1828 that the "modern ear" of chocolate making and production began. The introduction of cocoa powder not only made creating chocolate drinks much easier,but also made it possible to combine chocolate with sugar and then remix it with cocoa butter to create a solid.
