A French Yule Log – Daring Bakers Dec Challenge

The Daring Bakers came up with an ‘extreme’ challenge to end the year with a big bang! Last year they made a Yule Log out of cake, but this time it is a French Yule Log, which has several layers in it. When I first read the recipe I was sure I wasn’t going to make it, not because the challenge was intimidated but because I had no parties to take it to. In the nth moment, I made it finally, for a dinner at a friend’s place last night. It was a rush against time to get it done so I could post it before the month ends!

This month's challenge is brought to us by the adventurous Hilda from Saffron and Blueberry and Marion from Il en Faut Peu Pour Etre Heureux.They have chosen a French Yule Log by Flore from Florilege Gourmand.

FRENCH YULE LOG OR ENTREMETS RECIPE by Flore of Florilège Gourmand

In France you can buy two kinds of Yule log, either the Genoise and Buttercream type that we made last December, or what is more commonly purchased which is a frozen Yule Log very reminiscent of an ice cream cake, only often it’s not made of ice cream but rather frozen mousse of some sort. In French this is called an Entremets which is sometimes loosely translated in English as simply a cream dessert. This also means that this recipe is not holiday-specific, it is just a scrumptious dessert recipe.

This French Yule Log has six elements in it. And we were required to make all of the six elements (layers) and then assemble the log.

We were allowed various flavour and options and also different variations of chocolate; milk, dark or white chocolate.



Element #1 Dacquoise Biscuit (Almond Cake)
Preparation time: 10 mn + 15 mn for baking

Equipment: 2 mixing bowls, hand or stand mixer with whisk attachment, spatula, baking pan such as a 10”x15” jelly-roll pan, parchment paper

Note: You can use the Dacquoise for the bottom of your Yule Log only, or as bottom and top layers, or if using a Yule log mold (half-pipe) to line your entire mold with the biscuit. Take care to spread the Dacquoise accordingly. Try to bake the Dacquoise the same day you assemble the log to keep it as moist as possible.

Ingredients:
2.8 oz (3/4cup + 1Tbsp / 80g) almond meal
1.75 oz (1/2 cup / 50g) confectioner’s (caster) sugar
2Tbsp (15g) all-purpose flour
3.5oz (100g / ~100ml) about 3 medium egg whites
1.75 oz (4 Tbsp / 50g) granulated sugar

1.Finely mix the almond meal and the caster sugar. (If you have a mixer, you can use it by pulsing the ingredients together for no longer than 30 seconds).
2. Sift the flour into the mix.
3. Beat the eggs whites, gradually adding the granulated sugar until stiff.
4. Pour the almond meal mixture into the egg whites and blend delicately with a spatula.
5. Grease a piece of parchment paper and line your baking pan with it.
6. Spread the batter on a piece of parchment paper to an area slightly larger than your desired shape (circle, long strip etc...) and to a height of 1/3 inches (8mm).
7. Bake at 350°F (180°C) for approximately 15 minutes (depends on your oven), until golden.
8. Let cool and cut to the desired shape.

Element #2 Dark Chocolate Mousse (I did a combination of milk and white chocolate)
Preparation time: 20mn

Equipment: stand or hand mixer with whisk attachment, thermometer, double boiler or equivalent, spatula

Note: You will see that a Pate a Bombe is mentioned in this recipe. A Pate a Bombe is a term used for egg yolks beaten with sugar syrup, and then aerated. It is the base used for many mousse and buttercream recipes. It makes mousses and buttercreams more stable, particularly if they are to be frozen, so that they do not melt as quickly or collapse under the weight of heavier items such as the crème brulee insert.

Gelatin is the gelifying agent in all of the following recipes, but if you would like to use agar-agar, here are the equivalencies: 8g powdered gelatin = 1 (0.25 oz) envelope powdered gelatin = 1 Tbsp powdered gelatin = 1 Tbsp Agar-Agar.
1 Tbsp. of agar-agar flakes is equal to 1 tsp. of agar-agar powder.

Ingredients:
2.5 sheets gelatin or 5g / 1+1/4 tsp powdered gelatin
1.5 oz (3 Tbsp / 40g) granulated sugar
1 ½ tsp (10g) glucose or thick corn syrup
0.5 oz (15g) water
50g egg yolks (about 3 medium)
6.2 oz (175g) dark chocolate, coarsely chopped
1.5 cups (350g) heavy cream (35% fat content)

1. Soften the gelatin in cold water. (If using powdered gelatin, follow the directions on the package.)
2. Make a Pate a Bombe: Beat the egg yolks until very light in colour (approximately 5 minutes until almost white).
2a.Cook the sugar, glucose syrup and water on medium heat for approximately 3 minutes. (If you have a candy thermometer, the mixture should reach 244°F (118°C). If you do not have a candy thermometer, test the sugar temperature by dipping the tip of a knife into the syrup then into a bowl of ice water, if it forms a soft ball in the water then you have reached the correct temperature.
2b.Add the sugar syrup to the beaten yolks carefully by pouring it into the mixture in a thin stream while continuing to beat the yolks. You can do this by hand but it’s easier to do this with an electric mixer.
2c. Continue beating until cool (approximately 5 minutes). The batter should become thick and foamy.
3. In a double boiler or equivalent, heat 2 tablespoons (30g) of cream to boiling. Add the chopped chocolate and stir until melted and smooth.
4. Whip the remaining cream.
5. Pour the melted chocolate over the softened gelatin, mixing well. Let the gelatin and chocolate cool slightly and then stir in ½ cup (100g) of the whipped cream to temper. Add the Pate a Bombe.
6. Add in the rest of the cream (220g) mixing gently with a spatula.

Photo Update-

I was finally able to take a picture of a slice once the log was well frozen. You can now see the layers clearly, compared to before. I’m glad this came out nicely all ,and not as bad as it looked previously!!

Element #3 White Chocolate Ganache Insert
Preparation time: 10mn

Equipment: pan, whisk. If you have plunging mixer (a vertical hand mixer used to make soups and other liquids), it comes in handy.

Note: Because the ganache hardens as it cools, you should make it right before you intend to use it to facilitate piping it onto the log during assembly. Please be careful when caramelizing the sugar and then adding the cream. It may splatter and boil.

White Chocolate Ganache Insert
1.75 oz (4 Tbsp / 50g) granulated sugar
5 oz (135g) white chocolate, finely chopped
4.5 oz (2/3 cup – 1 Tbsp / 135g) heavy cream (35% fat content)

1. Make a caramel: Using the dry method, melt the sugar by spreading it in an even layer in a small sauce pan with high sides. Heat over medium-high heat, watching it carefully as the sugar begins to melt. Never stir the mixture. As the sugar starts to melt, swirl the pan occasionally to allow the sugar to melt evenly. Cook to dark amber color
2. While the sugar is melting, heat the cream until boiling. Pour cream into the caramel and stir thoroughly. Be very careful as it may splatter and boil.
3. Pour the hot caramel-milk mixture over the dark chocolate. Wait 30 seconds and stir until smooth.

Element #4 Praline Feuillete (Crisp) Insert
Preparation time: 10 mn (+ optional 15mn if you make lace crepes)

Equipment: Small saucepan, baking sheet (if you make lace crepes).
Double boiler (or one small saucepan in another), wax paper, rolling pin (or I use an empty bottle of olive oil).

Note: Feuillete means layered (as in with leaves) so a Praline Feuillete is a Praline version of a delicate crisp. There are non-praline variations below. The crunch in this crisp comes from an ingredient which is called gavottes in French. Gavottes are lace-thin crepes. To our knowledge they are not available outside of France, so you have the option of making your own using the recipe below or you can simply substitute rice krispies or corn flakes or Special K for them.

To make 2.1oz / 60g of gavottes (lace crepes - recipe by Ferich Mounia):
1/3 cup (80ml) whole milk
2/3 Tbsp (8g) unsalted butter
1/3 cup – 2tsp (35g) all-purpose flour
1 Tbsp / 0.5 oz (15g) beaten egg
1 tsp (3.5g) granulated sugar
½ tsp vegetable oil

1. Heat the milk and butter together until butter is completely melted. Remove from the heat.
2. Sift flour into milk-butter mixture while beating, add egg and granulated sugar. Make sure there are no lumps.
3. Grease a baking sheet and spread batter thinly over it.
4. Bake at 430°F (220°C) for a few minutes until the crepe is golden and crispy. Let cool.

Ingredients for the Praline Feuillete:
3.5 oz (100g) milk chocolate
1 2/3 Tbsp (25g) butter
2 Tbsp (1 oz / 30g) praline
2.1oz (60g) lace crepes(gavottes) or rice krispies or corn flakes or Special K ( I used the rice krispies)

1. Melt the chocolate and butter in a double boiler.
2. Add the praline and the coarsely crushed lace crepes. Mix quickly to thoroughly coat with the chocolate.
3. Spread between two sheets of wax paper to a size slightly larger than your desired shape. Refrigerate until hard.

Element #5 Vanilla Crème Brulée Insert
Preparation time: 15mn + 1h infusing + 1h baking

Equipment: Small saucepan, mixing bowl, baking mold, wax paper

Note: The vanilla crème brulée can be flavored differently by simply replacing the vanilla with something else e.g. cardamom, lavender, etc...

Ingredients:
1/2 cup (115g) heavy cream (35% fat content)
½ cup (115g) whole milk
4 medium-sized (72g) egg yolks
0.75 oz (2 Tbsp / 25g) granulated sugar
1 vanilla bean

1. Heat the milk, cream, and scraped vanilla bean to just boiling. Remove from the stove and let the vanilla infuse for about 1 hour.
2. Whisk together the sugar and egg yolks (but do not beat until white).
3. Pour the vanilla-infused milk over the sugar/yolk mixture. Mix well.
4. Wipe with a very wet cloth and then cover your baking mold (whatever shape is going to fit on the inside of your Yule log/cake) with parchment paper. Pour the cream into the mold and bake at 210°F (100°C) for about 1 hour or until firm on the edges and slightly wobbly in the center.
5. Let cool and put in the freezer for at least 1 hour to firm up and facilitate the final assembly.

Element #6 Milk Chocolate Icing
Preparation time: 25 minutes (10mn if you don’t count softening the gelatin)

Equipment: Small bowl, small saucepan

Note: Because the icing gelifies quickly, you should make it at the last minute.
For other gelatin equivalencies or gelatin to agar-agar equivalencies, look at the notes for the mousse component.

Element #6 Dark Chocolate Icing

Preparation time: 25 minutes (10mn if you don’t count softening the gelatin)
Equipment: Small bowl, small saucepan

Note: Because the icing gelifies quickly, you should make it at the last minute. For other gelatin equivalencies or gelatin to agar-agar equivalencies, look at the notes for the mousse component.

Ingredients:
4g / ½ Tbsp powdered gelatin or 2 sheets gelatin
¼ cup (60g) heavy cream (35 % fat content)
2.1 oz (5 Tbsp / 60g) granulated sugar
¼ cup (50g) water
1/3 cup (30g) unsweetened cocoa powder

1. Soften the gelatin in cold water for 15 minutes.
2. Boil the rest of the ingredients and cook an additional 3 minutes after boiling.
3. Add gelatin to the chocolate mixture. Mix well.
4. Let cool while checking the texture regularly. As soon as the mixture is smooth and coats a spoon well (it is starting to gelify), use immediately.

How To Assemble the French Yule Log

Depending on whether your mold is going to hold the assembly upside down until you unmold it or right side up, this order will be different.

THIS IS FOR UNMOLDING FROM UPSIDE DOWN TO RIGHT SIDE UP.
You will want to tap your mold gently on the countertop after each time you pipe mousse in to get rid of any air bubbles.

1) Line your mold or pan, whatever its shape, with rhodoid (plastic transparencies) OR plastic wrap. Rhodoid will give you a smoother shape but you may have a hard time using it depending on the kind of mold you’re using.
2) Cut the Dacquoise into a shape fitting your mold and set it in there. If you are using an actual Yule mold which is in the shape of a half-pipe, you want the Dacquoise to cover the entire half-pipe portion of the mold.
3) Pipe one third of the Mousse component on the Dacquoise.
4) Take the Creme Brulee Insert out of the freezer at the last minute and set on top of the mousse. Press down gently to slightly ensconce it in the mousse.
5) Pipe second third of the Mousse component around and on top of the Creme Brulee Insert.
6) Cut the Praline/Crisp Insert to a size slightly smaller than your mold so that it can be surrounded by mousse. Lay it on top of the mousse you just piped into the mold.
7) Pipe the last third of the Mousse component on top of the Praline Insert.
8) Freeze for a few hours to set. Take out of the freezer.
9) Pipe the Ganache Insert onto the frozen mousse leaving a slight edge so that ganache doesn’t seep out when you set the Dacquoise on top.
10) Close with the last strip of Dacquoise.

Freeze until the next day.


THE NEXT DAY:

Unmold the log and set on a wire rack over a shallow pan.
Cover the cake with the prepared icing.
Let set and return to the freezer.
Decorate the cake/log -- I drizzled left over milk chocolate ganache on top of the log. I made the dark chocolate hearts but pouring out the remaining icing on a sheet. I let it set and then cut it with a heart shaped cookie cutter.
Transfer to the refrigerator no longer than ½ hour before serving as it may start to melt quickly depending on the elements you chose.

The mousse element began to melt while taking pics, hence the mess up in layers. (Update: I took a pic after the log was well frozen-- see above) The next time I will make sure I don't attempt any DB challenges in the last moment...this one almost fell apart on me! But all in all, the log was great taste wise and elements wise.

Phew, I almost missed this challenge,glad I could complete it!! :)

Wishing all of you a wonderful and peaceful New Year!
