I am adding this to my cookbook for safekeeping. I have not tried it yet, but will be trying it for an upcoming party. This recipe was originally adapted from Louisiana Real and Rustic Cookbook, by Emeril Lagasse, with Mercelle Bienvenu.
In a plastic gallon container, with a lid, combine the brandy, bourbon, rum and half and half, and vanilla. Sweeten the cream mixture to taste with the simple syrup. Cover and freeze until slightly frozen. To serve, using an ice pick, (carefully) slush the mixture. Spoon into balloon wine glasses and garnish with nutmeg.
