I think the most challenging thing for me this month was finding time to complete it! Otherwise, the pound cake and ice cream were pretty simple. It is just a basic recipe for each. The only different (challenging) parts were browning the butter (since I’ve only done it a few times), and freezing the ice cream, since I do not have an ice cream machine (yet!).
Since I made the ice cream (custard) and just let it freeze over night (no stirring involved) and I took it out the next morning and paddled it on the electric mixer for a few minutes to aerate it and help to somewhat melt out the ice crystals that formed. This help make it look more like vanilla ice cream. Before it “churned” it was just yellow and the vanilla bean had all sunk to the bottom of the container. Literally, just frozen custard. After, it was white and the little “dots” of vanilla were disbursed throughout. It was more creamy, and less icy, but still not perfect. I think the smooth, non-icy texture can only be achieved with a real way of churning it while it freezes. Not bad though, for homemade ice cream without any sort of ice cream machine.
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”.
I made the petit fours (but did not make/use the chocolate glaze). I think they’re good just as they are!
The pound cake calls for cake flour. You can make 1 cup of cake flour by placing 2 tablespoons of corn starch in a 1 cup measure, and filling to the top with all purpose flour.
Ice cream – 45 min active time, ice cream rests/chills for 1 hour then overnight. Without an ice cream maker, the ice cream chills 2-3 hours and must be stirred every 30 minutes.
Brown Butter Pound Cake – 2 hours (includes cooling time)
Chocolate Glaze – 15 minutes
Meringue – 10 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.
Assembly of Baked Alaska – Ice cream must be frozen head of time several hours, then the Baked Alaska is frozen 1 hour or up to one day.
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.
Meringue (For the Baked Alaska)
8 large egg whites
½ teaspoon (3g) cream of tartar
½ teaspoon (3g) salt
1 cup (220g) sugar
Beat the egg whites, cream of tartar, and salt on high speed in an electric mixer until soft peaks form. Beat in the sugar gradually in a slow stream until stiff peaks form.
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.
Assembly Instructions – Baked Alaska
1. Line four 4” (10cm) diameter tea cups with plastic wrap, so that plastic wrap covers all the sides and hangs over the edge. Fill to the top with ice cream. Cover the top with the overhanging plastic wrap and freeze for several hours, or until solid.
2. Level the top of the brown butter pound cake with a serrated knife or with a cake leveler. Cut out four 4” (10cm) diameter circles from the cake. Discard the scraps or use for another purpose.
3. Make the meringue (see above.)
4. Unwrap the ice cream “cups” and invert on top of a cake round. Trim any extra cake if necessary.
5. Pipe the meringue over the ice cream and cake, or smooth it over with a spatula, so that none of the ice cream or cake is exposed. Freeze for one hour or up to a day.
6. Burn the tips of the meringue with a cooking blow torch. Or, bake the meringue-topped Baked Alaskas on a rimmed baking sheet in a 500°F/260°C oven for 5 minutes until lightly golden. Serve immediately.
