Cherry Ice Cream

Directions

1. Prepare an ice bath; set aside. Split the vanilla bean lengthwise with a sharp paring knife. Gently scrape out all the seeds. Whisk together 1/2 cup sugar with the yolks; set aside.
2. Place the vanilla bean scrapings and pod in a medium saucepan with the cream, milk, and the remaining 1/2 cup sugar and pinch of salt. Bring the milk mixture just to a simmer. Using a measuring cup or a ladle, slowly pour about 1/2 cup of the hot milk mixture into the egg-yolk mixture, whisking constantly. Keep adding milk mixture, about 1/2 cup at a time until it has all been added.
3. Pour mixture back into saucepan, and cook over low heat, stirring constantly with a wooden spoon, until mixture is thick enough to coat the back of a spoon, 3 to 5 minutes. The custard should retain a line drawn across the back of the spoon with your finger. Pour through a mesh sieve into a medium bowl set in the ice bath; discard vanilla bean. Stir occasionally until cooled. Whisk in cherry concentrate and corn syrup or glucose. Cover, and transfer to refrigerator until chilled, at least 1 hour and up to overnight.
4. Pour into an ice-cream maker, and add poached cherries. Process according to manufacturer's instructions until set but not hard.
5. Transfer the soft ice cream to a plastic container; freeze for at least 4 hours and up to overnight.
