Is 2008 really coming to an end? When I look back on the year, it's hard to believe that we're about to close this chapter in our lives. I can't imagine a better way to say goodbye to 2008 than with a challenging day in the kitchen, courtesy of The Daring Bakers, of course.
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.
What is a French Yule Log?
In France you can buy two kinds of Yule log, either the Genoise and Buttercream type, 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 also just a scrumptious dessert recipe.
This recipe comes almost entirely from the website, Florilège Gourmand, which belongs to Flore. Her website is in French and different portions of the recipe have been pulled from the recipes in the entremets section.
Be brave, take a deep breath, and give this French Yule Log a try.
FRENCH YULE LOG OR ENTREMETS RECIPE by Flore of Florilège Gourmand
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: Try to bake the Dacquoise the same day you assemble the log to keep it as moist as possible.
2.8 oz (3/4cup + 1Tbsp / 80g) almond meal
1.75 oz (1/2 cup / 50g) confectioner’s 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 confectioner's 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
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 a sugar syrup, 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.
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 remainder of the cream until stiff.
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 WHIPPED cream to temper. Add the Pate a Bombe.
6. Add in the rest of the DWHIPPE cream (220g) mixing gently with a spatula.
Element #3 Dark 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.
1.75 oz (4 Tbsp / 50g) granulated sugar
4.5oz (2/3 cup – 1 Tbsp/ 135g) heavy cream (35% fat content)
5 oz (135g) dark chocolate, finely chopped
3Tbsp + 1/2tsp (45g) unsalted butter softened
1. Make a caramel: Using the dry method, melt the sugar by spreading it in an even layer in a small saucepan 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 (for most of you that means darker than last month’s challenge).
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.
4. Add the softened butter and whip hard and fast. The chocolate should be smooth and shiny.
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 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)
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.
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...
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. Bake in a water bath.
5. Let cool and put in the freezer for at least 1 hour to firm up and facilitate the final assembly.
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.
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.
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 (clear hard plastic, I usually use transparencies cut to the desired shape, it’s easier to find than cellulose acetate which is what rhodoid translates to in English) OR plastic film. 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) Pipe one third of the Mousse component into the mold.
3) 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.
4) Pipe second third of the Mousse component around and on top of the Creme Brulee Insert.
5) 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.
6) Pipe the last third of the Mousse component on top of the Praline Insert.
7) Freeze for a few hours to set. Take out of the freezer.
8) 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.
9) Close with the Dacquoise.
Freeze until the next day.
If you are doing the assembly UPSIDE DOWN with ONE piece of Dacquoise on the BOTTOM ONLY the order is:
2) Creme Brulee Insert
4) Praline/Crisp Insert
6) Ganache Insert
THE NEXT DAY...
Unmold the cake/log/whatever and set on a wire rack over a shallow pan.
Cover the cake with the icing.
Let set. Return to the freezer.
You may decorate your cake however you wish. The decorations can be set in the icing after it sets but before you return the cake to the freezer or you may attach them on top using extra ganache or leftover mousse, etc...
Transfer to the refrigerator no longer than ½ hour before serving as it may start to melt quickly depending on the elements you chose.
