Makes about 5 cups
Source: Molto Gusto: Easy Italian Cooking by Mario Batali and Mark Ladner

2 cups milk
½ cup sugar
½ cup corn syrup
1¾ cups (14 ounces) crème fraîche (see note)
½ teaspoon salt

Combine the milk, sugar and corn syrup in a medium saucepan and heat over medium heat, stirring, until the sugar is dissolved and the temperature registers 160 degrees on an instant-read thermometer. Pour the mixture into a heatproof bowl and chill over an ice bath, stirring occasionally, until cold.

Using an immersion blender or a whisk, mix the crème fraîche and salt into the milk mixture. Strain through a fine-mesh strainer into another bowl or container, cover and refrigerate for at least six hours or, preferably, overnight. Whisk the crème fraîche mixture until smooth. Freeze the gelato in an ice cream maker according to the manufacturer's instructions. Transfer to an airtight container and freeze one hour before serving.

Note: For homemade crème fraîche, combine four parts heavy cream with one part buttermilk (~1 1/3 c and 1/3 c, respectively) in a covered container and let it stand at a cool room temperature (65 to 70 degrees) for 24 to 36 hours, until it thickens and sours slightly. Stir it well and refrigerate. It'll keep for one week.
