I actually wasn't crazy about this recipe. What is different about the frozen custard I make at home and the frozen custard I buy at Culver's or Fritz's or Freddy's? My home version coats the inside of my mouth and tastes very egg-y and I really prefer the non-custard way. I do however think I would make this again and use a different recipe- old faithful- and add the blueberry marble to that instead.
Blueberry Vanilla Swirl Ice Cream
4 egg yolks
1 cup heavy cream
1 cup whole milk
1/2 cup sugar
1 vanilla bean or 1 Tb vanilla paste
1 cup blueberries (fresh or frozen)
1/4 cup sugar
In a large bowl, whisk the egg yolks and sugar until pale and thick. Run a knife through the center of the vanilla bean, not cutting all the way through, split it open and with the tip of a pairing knife, scrape the seeds. Place them in a saucepan over medium heat, add the milk and cream to boiling point but do not let it boil. Slowly pour the hot cream onto the egg yolks mixture and stir to combine (tempering). Pour the whole mixture back into the saucepan and cook over low heat, stirring constantly, until the cream coats the back of spoon. At this point you have a thick custard sauce. Remove from the heat and let cool completely, refrigerate until cold, or overnight.
In the meantime prepare the blueberries: in a small saucepan, combine the berries and the sugar and cook over medium low heat until the berries start to pop and release their natural juices. Let cool completely.
Process the custard according to your ice cream maker manufacturer's instructions and towards the last couple of minutes of churning time pour in the cooled blueberries and give it a couple of swirls. Pour the soft ice cream into a freezer safe container until it reaches your preferred consistency.
If you do not have an ice cream machine: take care of the vanilla ice cream first, during your last whipping, add the blueberries the same way and freeze.
