Guinness Chocolate Ice Cream

Instructions

To make the whipped cream: In a large metal bowl, beat together cream and 3 tablespoons sugar until soft peaks form. Transfer to the refrigerator to keep chilled.

To make the egg mixture: In stand mixer fitted with a paddle attachment and on medium high speed, beat the eggs and ¼ cup sugar until mixture falls in ribbons when the paddle is lifted, about 5 to 7 minutes.

In the meantime, place a saucepan over medium high heat, add
the water and remaining ½ cup of sugar, stir just until the sugar is moistened. Let the mixture cook without stirring, every now and again, using the handle tilt and swirl the pot. Bring the mixture to 245 degrees F, about 3 to 4 minutes.

To make the sugar syrup: Once the syrup is ready, turn the mixer speed to low and with mixer running, slowly pour the syrup down the side of the bowl in a steady stream. Once the syrup is fully added, turn the mixer speed to medium high and continue to beat until mixture falls in ribbon when the paddle is lifted, about 8-10 minutes.  

Place chocolate custard in large bowl and fold in half of the egg mixture until homogenous. Add remaining half of egg mixture and fold until homogenous.

Remove the whipped cream from the refrigerator and fold it into the chocolate-egg mixture until homogenous.

Scrape chocolate ice cream mixture into an 8 or 9-inch loaf
pan. Place in freezer to freeze overnight.

Chocolate Custard

½ cup Guinness Draught, measured without the head

¾ cup granulated sugar, plus 3 tablespoons, divided use

2 cups heavy cream

¾ cup Dutch process cocoa powder

3 oz. chocolate, at least 70% cacao

¾ cup granulated sugar

6 tablespoons unsalted butter, cut into 1-inch pieces

2 tablespoons firmly packed brown sugar

1 large egg

1 egg yolk

Preparation: Heat oven to 300 F.

In a medium saucepan, over medium heat, stir together the Guinness Draught and 3 tablespoons sugar. Bring mixture to a bowl and reduce by one-third. Remove pan from heat and stir in heavy cream, cocoa powder, chocolate, remaining ¾ cup granulated sugar, butter and brown sugar.

Return pan stovetop and over medium low heat, cook and stir
continuously until mixture just starts to simmer around the edges, about 8 to 10 minutes.

In large bowl, whisk together egg and egg yolk. Temper the egg mixture by adding in 2 tablespoons of the of custard while whisking vigorously and constantly. Continue to add 2 tablespoons at a time and whisk for at least 30 seconds after each addition, up until one-fourth of the mixture is added. Then whisk in the remaining chocolate mixture.

Pour mixture into an 8-inch round pan. Transfer pan to the
oven and bake for 15 to 20 minutes.

In the meantime, prepare a water bath by adding water and ice into a large mixing bowl.

Remove the baked chocolate custard from the oven and scrape
it into a fresh mixing bowl and blend it with an immersion blender (or scrape into a blender and process until smooth).

Place bowl with the blended chocolate mixture into the water bath (if using a blender, scrape mixture into a bowl and then set in the water bath) for 15 minutes. This will stop the custard from cooking any further.

Remove chocolate custard from water bath and place a piece of plastic wrap directly on the surface to prevent a skin from forming. Chocolate custard can be stored for up 4 days or frozen for a month.
