Raspberry Gelato

This recipe was originally published by Cuisinart.

ingredients

• 4 cups red raspberries
• 1 cup granulated sugar
• 2-1/4 cups half-and-half, divided
• 6 large egg yolks
• 1/4 cup fat-free powdered milk
• 1 cup heavy cream
• 2 teaspoons pure vanilla extract
• 1-2 drops red food coloring, optional (will enhance color)

directions

1. Place raspberries in a food processor fitted with the metal "s" blade or in a blender (if using a blender, 2 cups at a time for best results). Process until completely puréed and smooth. Press raspberry purée through a fine mesh sieve or chinois with a wooden spoon or spatula. Discard seeds -- you will have approximately 2 cups red raspberry purée; reserve.
2. Place the sugar and 1 1/4 cups of the half-and-half in a 2 1/2 quart saucepan with a heavy bottom. Bring to a simmer over medium heat and stir to dissolve the sugar. Keep warm over low heat. Place the egg yolks in a medium bowl and whisk until thickened, about 2 minutes (can use a hand or stand mixer fitted with the whip on low speed). While whisking, add 1/2 cup of the hot half-and-half/sugar mixture and whisk until blended. Stir the egg mixture back into the saucepan; increase heat to medium. Stir the mixture constantly with a wooden spoon, until the mixture is thickened like a custard sauce and registers 180 °F when checked with an instant-read thermometer.
3. Stir in remaining half-and-half, powdered milk and heavy cream.
4. Strain the mixture through a fine mesh strainer; stir in reserved raspberry purée, vanilla, and food coloring. Cover and refrigerate at least 6 hours before continuing.
5. Turn the machine on; pour mixture into freezer bowl, and let mix until thickened, about 20 to 25 minutes. The gelato will have a soft, creamy texture. If a firmer consistency is desired, transfer the gelato to an airtight container and place in freezer for about 2 hours. Remove from freezer about 15 minutes before serving.
