Concord Grape Swirl Ice Cream Recipes

Steps:

• Make the Jam and Syrup: Mash grapes with sugar and vitamin C powder, if using. Cover bowl and let stand at room temperature for 1 hour or refrigerated overnight.
• Transfer grape mixture to a small saucepan and bring to a boil over medium-high heat. Reduce heat and simmer until thickened and grapes burst, 5 to 10 minutes. Strain liquid through a fine-mesh sieve into a bowl. Set sieve over another bowl and, using a plastic bowl scraper, press the grapes through the sieve to remove seeds and skin and create a jam. You should have about 1/2 cup liquid syrup and 3/4 cup grape jam. Cover and transfer both bowls to refrigerator for at least 1 hour and up to overnight.
• Make the Custard: In a large bowl, whisk together egg yolks and 6 tablespoons sugar until pale yellow; set aside.
• In a large saucepan, whisk together milk, cream, remaining 6 tablespoons sugar, vanilla bean, and seeds. Bring mixture to a boil over medium-high heat. As soon as mixture begins to rise up the sides of the pan, remove from heat.
• Whisk 1 cup of the hot milk mixture slowly into the reserved egg yolk mixture; whisk to combine. Slowly whisk egg mixture into saucepan with remaining hot milk mixture; whisk in salt. Transfer custard mixture to a large bowl; cover and chill until very cold, at least 8 hours and up to overnight.
• Add grape syrup to chilled custard and whisk to combine; strain through a fine-mesh sieve and discard solids.
• Transfer grape jam to a large metal bowl and transfer to freezer; freeze until firm but not solid.
• Transfer custard to an ice cream maker; freeze according to manufacturer's instructions. Transfer ice cream to bowl with semifrozen jam and fold with a rubber spatula to combine. Transfer to an airtight container and keep frozen until ready to serve, up to 5 days.

Steps:

• Purée half of grapes in a blender until smooth, then force through a fine-mesh sieve into a bowl, discarding solids. Repeat with remaining grapes to yield 3 cups purée. Whisk in sugar until dissolved. Chill until very cold, 3 to 6 hours.
• Freeze in ice cream maker, then transfer to an airtight container and put in freezer to firm up, at least 2 hours.

Steps:

• Prepare an ice bath; set aside. Combine grapes and the water in a medium saucepan. Cook over medium-high heat until the liquid begins to bubble and grapes start releasing liquid, about 4 minutes. Reduce heat, and simmer until juices are dark purple and grapes begin to break apart, about 3 minutes.
• Pass mixture through a food mill and then through a fine sieve into a large bowl set in the ice bath; stir frequently until completely cool. Stir in simple syrup and lemon juice.
• Transfer mixture to an ice-cream maker, and freeze according to manufacturer's instructions. Transfer to an airtight container, and store in the freezer until ready to serve, up to 2 weeks.
