We are offering light chocolate. Bittersweet chocolate is essentially a form of dark chocolate to which some sugar (typically 13), more cocoa butter, and semisweet chocolate is basically a dark chocolate with a low (typically 12) sugar content. bittersweet chocolate usually has less sugar and more liquor than semisweet chocolate, but the two names are used interchangeably. One manufacturer’s “bittersweet” bar may taste sweeter than another’s “semi-sweet” bar.
