   Place chocolate and vanilla in the bowl of a stand mixer. Combine sugar, corn syrup, and 1/2 cup of the half-and-half in a saucepan over medium-high; bring to a boil, stirring until sugar dissolves. Cook, without stirring, until a candy thermometer inserted in mixture registers 230u00b0F, about 15 minutes. Stir in butter, salt, and remaining 3/4 cup half-and-half. Cook, without stirring, until mixture reaches 236u00b0F, about 20 minutes. Pour sugar mixture over chocolate mixture. (Do not stir together.) Let stand until mixture reaches 110u00b0F, about 30 minutes. Beat on medium-low speed until mixture is thick and beginning to become firm, 8 to 10 minutes. Quickly beat in walnuts. Transfer fudge to prepared dish; smooth top. Cover and let stand at room temperature 8 hours or overnight.
