Daring Bakers 32nd Challenge: Ice cream petit fours

The August 2010 Daring Bakers’ challenge was hosted by Elissa of 17 and Baking. For the first time, The Daring Bakers partnered with Sugar High Fridays for a co-event and Elissa was the gracious hostess of both. Using the theme of beurre noisette, or browned butter, Elissa chose to challenge Daring Bakers to make a pound cake to be used in either a Baked Alaska or in Ice Cream Petit Fours. The sources for Elissa’s challenge were Gourmet magazine and David Lebovitz’s “The Perfect Scoop”.

This month’s challenge involved making ice cream once more. I was surprised by this ice cream recipe, mostly by the fact that the cream never gets cooked, but just mixed in at the end. Odd, I thought. But I was game to try it. I love the taste and smell of brown butter, so making the pound cake was simple enough. I followed the ice cream recipe, and it seemed to have come out ok. That’s where things got a little astray. I built this dessert over 4 days, due to a busy schedule that week. Which caused my cake to dry out a bit in the fridge. Which caused it to not stick properly to the ice cream, even after the requisite freezing time. Which caused the layers to fall apart when I tried to dip them into the warm chocolate ganache. The fact that I cut the squares too small (sorry, but where I come from, petit fours are, well, petit) didn’t help either. After a couple of attempts at dipping, I quickly realized a very frustrating time was ahead, and bailed by dumping the chocolate over the cut squares. There. Challenge completed. Sorta. (i had spent the week battling uncooperative tables and borders in Word at work, and my patience was running very thin.) I put everything back into the freezer and later broke off sections and stored in plastic containers. I confesss I threw out most it. The ice cream came out icy in the end, despite using my ice cream maker. This cream-at-the-end business still doesn’t feel right. Certainly didn’t taste right. So, conclusion: great recipe for the cake part, I’ll stick to my crème anglaise recipe for vanilla ice cream, and will try to do everything in one go next time.

Ice cream petit fours

Brown Butter Pound Cake – 2 hours (includes cooling time)

Chocolate Glaze – 15 minutes

Assembly of Ice Cream Petit Fours – Ice cream must be frozen ahead of time several hours, then the cake and ice cream freeze overnight. After dipping, the petit fours freeze for one hours.

Equipment required:
• Small and medium saucepans
• Paring knife
• 2 quart (2 litres) bowl
• Electric mixer
• Whisk
• Spatula
• Sieve
• 9”x9” (23cmx23cm) square baking pan
• 10” (25 cm) skillet
• Cake leveler/serrated knife
• Cooling racks
• Rimmed half sheets
• Teacups
• Plastic wrap
• Piping bags (optional)
• Ice cream maker (optional)
• Cooking blow torch (optional)

Directions:

Vanilla Ice Cream

1 cup (250ml) whole milk
A pinch of salt
3/4 cup (165g) sugar
1 vanilla bean, split lengthwise OR 2 teaspoons (10ml) pure vanilla extract
2 cups (500ml) heavy (approx 35% butterfat) cream
5 large egg yolks
1 teaspoon (5ml) pure vanilla extract

1. Heat the milk, salt, and sugar in a medium saucepan until the liquid steams. Scrape out the seeds of the vanilla bean with a paring knife and add to the milk, along with the bean pod. Cover, remove from heat, and let infuse for an hour. (If you do not have a vanilla bean, simply heat the milk, salt, and sugar in a medium saucepan until the liquid steams, then let cool to room temperature.)

2. Set up an ice bath by placing a 2-quart (2 litre) bowl inside a large bowl partially filled with water and ice. Put a strainer on top of the smaller bowl and pour in the cream.

3. In another bowl, lightly beat the egg yolks together. Reheat the milk in the medium saucepan until warmed, and then gradually pour ¼ cup warmed milk into the yolks, constantly whisking to keep the eggs from scrambling. Once the yolks are warmed, scrape the yolk and milk mixture back into the saucepan of warmed milk and cook over low heat. Stir constantly and scrape the bottom with a spatula until the mixture thickens into a custard which thinly coats the back of the spatula.

4. Strain the custard into the heavy cream and stir the mixture until cooled. Add the vanilla extract (1 teaspoon [5ml] if you are using a vanilla bean; 3 teaspoons [15ml] if you are not using a vanilla bean) and refrigerate until thoroughly chilled, preferably overnight.

5. Remove the vanilla bean and freeze in an ice cream maker. If you don’t have an ice cream maker, you can make it without a machine. See instructions from David Lebovitz: http://www.davidlebovitz.com/archives/2007/07/making_ice_crea_1.html

Brown Butter Pound Cake

19 tablespoons (9.5 oz) (275g) unsalted (sweet) butter
2 cups (200g) sifted cake flour (not self-rising; sift before measuring) (See “Note” section for cake flour substitution)
1 teaspoon (5g) baking powder
1/2 teaspoon (3g) salt
1/2 cup (110g) packed light brown sugar
1/3 (75g) cup granulated sugar
4 large eggs
1/2 teaspoon pure vanilla extract

1. Preheat the oven to 325°F/160°C and put a rack in the center. Butter and flour a 9”x9” (23cmx23cm) square pan.

2. Place the butter in a 10” (25cm) skillet over medium heat. Brown the butter until the milk solids are a dark chocolate brown and the butter smells nutty. (Don’t take your eyes off the butter in case it burns.) Pour into a shallow bowl and chill in the freezer until just congealed, 15-30 minutes.

3. Whisk together cake flour, baking powder, and salt.

4. Beat the brown butter, light brown sugar, and granulated sugar in an electric mixer until light and fluffy, about 2 minutes. Beat in the eggs one at a time, mixing well, and then the vanilla extract.

5. Stir in the flour mixture at low speed until just combined.

6. Scrape the batter into the greased and floured 9”x9” (23cmx23cm) square pan. Smooth the top with a rubber spatula and rap the pan on the counter. Bake until golden brown on top and when a toothpick inserted into the center comes out clean, about 25 minutes.

7. Cool in the pan 10 minutes. Run a knife along the edge and invert right-side-up onto a cooling rack to cool completely.

Chocolate Glaze (For the Ice Cream Petit Fours)

9 ounces (250g) dark chocolate, finely chopped
1 cup (250 ml) heavy (approx 35% butterfat) cream
1 1/2 tablespoons (32g) light corn syrup, Golden syrup, or agave nectar
2 teaspoons (10ml) vanilla extract

Stir the heavy cream and light corn syrup in a small saucepan over medium heat until it comes to a boil. Remove from heat and add the dark chocolate. Let sit 30 seconds, then stir to completely melt the chocolate. Stir in the vanilla and let cool until tepid before glazing the petit fours.

Assembly Instructions – Ice Cream Petit Fours

1. Line a 9”x9” (23cmx23cm) pan with plastic wrap, so that no sides of the pan are exposed and so there is some extra plastic wrap hanging off the sides. Spread 1 ¾ to 2 cups (450ml to 500ml) ice cream into the pan. Cover with more plastic wrap and freeze several hours.

2. Once the brown butter pound cake has completely cooled, level the top with a cake leveler or a serrated knife. Then split the cake in half horizontally to form two thin layers.

3. Unwrap the frozen ice cream. Flip out onto one of the layers of cake and top with the second layer of cake. Wrap well in plastic wrap and return to the freezer overnight.

4. Make the chocolate glaze (see above.)

5. While the glaze cools, trim ¾” (2cm) off each side of the ice cream cake to leave a perfectly square 7.5” (19cm) ice cream cake. Cut the cake into twenty five petit fours, each 1.5”x1.5” (4cmx4cm).

6. Glaze the petit fours one at a time: place a petit four on a fork and spoon chocolate glaze over it.

7. Place the petit fours on a parchment-lined baking sheet and return to the freezer for one hour.
