In a medium saucepan set over medium-low heat, whisk together the milk, cream, half of the sugar, salt and the scraped vanilla bean (including the pod). Bring the mixture just to a boil.
While the milk/cream mixture is heating, combine the yolks and remaining sugar in a medium bowl. Using a hand mixer on low speed or whisk, beat until mixture is pale and thick.
Once the milk/cream mixture has come to a slight boil, whisk about 1∕3 of the hot mixture into the yolk/sugar mixture. Add another 1∕3 of the mixture, then return the combined mixture to the saucepan. Using a wooden spoon, stir the mixture constantly over low heat until it thickens slightly and coats the back of the spoon. This mixture must NOT boil or the yolks will overcook – the process should only take a few minutes.
Turn on the Cuisinart® ice cream maker; pour the mixture into the frozen freezer bowl and let mix until thickened, about 20 minutes. The ice cream will have a soft, creamy texture. If a firmer consistency is desired, transfer the ice cream to an airtight container and place in freezer for about 2 hours. Remove from freezer about 15 minutes before serving
