French Yule Log or Entremets by Flore of Florilège Gourmand
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 Florilège Gourmand!
What is a French Yule Log? According to our hostesses, you can buy two kinds of Yule log in France, the Genoise or Buttercream type. However, what is more commonly purchased 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 sometime loosely translated in English as simply as a cream dessert. This also means that this recipe is not holiday specific - it is just a scrumptious dessert recipe that you can enjoy year round!
The recipes of most elements come almost entirely from Florilège Gourmand, which belongs to Flore, except for one small labeled portion and some of the variations courtesy of our dear Daring Baker fairy Tartelette. Different recipes have been pulled from the entremet section of Flore’s site to make up this masterpiece. Also, since Flore’s blog is written in French, hugs to the hostesses for the translation! Thank you ladies for choosing this beautiful and absolutely scrumptious dessert!
Before we begin, I just want to let you know that this may look impossible to complete but I assure you that this looks 100 times harder than it really is! The key to success is organization! As long as you complete each element in the order that it calls for, you are half way there, what is left is how to assemble and to decorate. On top of this, I strongly advise you to break the elements into 2 days so you have enough time to draft up the final look of this dessert. You see, I bake the crème brûlée and make the chocolate praline crisp the night before and let them set in the refrigerator. Bake the dacquoise biscuit the next morning, while it is being cool, I whipped up the mousse. Assemble these elements and let set in the fridge. Meanwhile, make the ganache and complete the log composition. Later in the afternoon, demold and cover the log with glaze to complete it. Decorate it an hour before serving.
Now, enjoy the ooh and ahh from your friends and family, my dear^^
Here are the rules for the CHALLENGE - MUST MAKE ALL 6 of the following elements for the log:
1) dacquoise biscuit
3) ganache Insert
4) praline (Crisp) Insert
5) crème brûlée Insert
Some things to keep in mind:
- You are of course free to flavor your layers differently, we realize not everyone likes chocolate; it was just the simplest way to introduce variations. You will notice there are fruit variations in a couple of the components, you may of course do fruit flavoring for all of them, but we can’t guarantee we know exactly how to change the recipe in that case, so bear with us and we’ll try to help you out as much as possible.
- PLEASE READ THE NOTES AT THE BEGINNING OF EVERY SECTION. They should help you with most questions you may have, at least we hope.
- Please look at the pictures of the “new” components in this recipe that you may never have seen before and at a completed log courtesy of Marion running a test at the very end of the recipe.
- We’ve tried to give you as many measuring units as possible (this recipe started out in grams only). We hope this helps. Imperial units (tbsp etc…) are American.
- For all our alternative bakers, the recipe is so long we didn’t know where to start even asking Nathalie to do a gluten-free one, so please feel free to ask, we’ll do our best to help you.
Element #1 ~ Praline Feuillete (Crisp) Insert
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. If you want to make your own praline, please click here.
Gavottes (lace crepes - recipe by Ferich Mounia) yields 60g
1/3cup (80ml) whole milk
2/3tbsp (8g) unsalted butter
1/3cup minus 2tsp (35g) all-purpose flour
1tbsp (15g) beaten egg
1tsp (3.5g) granulated sugar
½tsp 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.
Chocolate Praline Feuillete:
100g bittersweet chocolate
1 + 2/3tbsp (25g) unsalted butter
2tbsp (30g) praline
60g gavottes or 2tbsp rice krispies or corn flakes
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 #2 ~ Jasmine-infused Crème Brulée Insert
Note: The crème brulée can be flavored differently by simply replacing the jasmine with something else e.g. cardamom, lavender, etc...
½ cup (115g) heavy cream
½ cup (115g) whole milk
4 med (72g) egg yolks
2tbsp (25g) granulated sugar
1tsp premium loose jasmine tea leave
1. Heat the milk, cream, and jasmine tea leave to just boiling. Remove from the heat and let the jasmine infuse for about 12 minutes.
2. Whisk together the sugar and egg yolks (but do not beat until white).
3. Pour the jasmine-infused milk over the sugar/yolk mixture and mix well.
4. Wipe with a very wet cloth and then cover your baking mold (whatever shape is going to fit on the inside your Yule log/cake) with parchment paper. Place it into a large roasting pan then pour hot water into the roasting pan all the way up half way of the baking mold. Pour the cream into the mold and bake at 210°F (100°C) for about 1 ½ 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.
Tartelette says: You can bake it without a water bath since it is going to go inside the log (the aesthetics of it won't matter as much since it will be covered with other things)....BUT I would recommend a water bath for the following reasons:
- you will get a much nicer mouth feel when it is done
- you will be able to control its baking point and desired consistency much better
- it bakes for such a long time that I fear it will get overdone without a water bath
Now...since it is baked in a pan and it is sometimes difficult to find another large pan to set it in for a water bath, even a small amount of water in your water bath will help the heat be distributed evenly in the baking process. Even as little as 1 inch will help.
Element #3 ~ Dacquoise Biscuit (Almond Cake)
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.
¾ cup + 1Tbsp (80g) almond meal
½ cup (50g) confectioner’s sugar
2tbsp all-purpose flour
3tbps unsweetened cocoa powder, sifted
100g about 3 med egg whites
4tbsp (50g) granulated sugar
1. In a mixer, pulse the together the almond meal and the confectioner's sugar for no longer than 30 seconds then sift in the unsweetened cocoa powder. Finely mix all ingredients until incorporated.
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 #4 ~ Bittersweet Chocolate Mousse
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 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. In the Vanilla Mousse variation, pastry cream is made to the same effect. In the Mango Mousse variation, Italian meringue is made to the same effect. Italian meringue is a simple syrup added to egg whites as they are beaten until stiff. It has the same consistency as Swiss meringue (thick and glossy) which we have used before in challenge recipes as a base for buttercream. The whipped Cream option contains no gelatin, so beware of how fast it may melt.
Gelatin/Gelatine 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.
2.5 sheets gelatin or 5g powdered gelatin
3 tbsp (40g) granulated sugar
1 ½ tsp (10g) glucose or thick corn syrup
1tbsp (15g) water
50g (3 med.) egg yolks
175g bittersweet chocolate, coarsely chopped
1.5 cups (350g) heavy cream
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 color (approximately 5 minutes until almost white).
3. 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.4. 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. Continue beating until cool (approximately 5 minutes). The batter should become thick and foamy.3. In a double boiler or equivalent, heat 2 tablespoons of cream to boiling then 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 of WHIPPED cream to temper then add the Pate a Bombe.
6. Add in the rest of the WHIPPED cream mixing gently with a spatula until incorporated.
Element #5 ~ Jasmine-infused Dark Chocolate Ganache Insert
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.
4tbsp (50g) granulated sugar
1tsp premium loose jasmine tea leave
135g dark chocolate, finely chopped
3tbsp + ½ tsp (45g) unsalted butter softened
2/3 cup minus 1tbsp (135g) heavy cream
1. Add the jasmine tea leave to the heavy cream and let steep in the fridge overnight. Strain before use. 2. 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 jasmine infused 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 (if you have a plunging mixer use it). The chocolate should be smooth and shiny.
Element #6 ~ Dark Chocolate Glaze/Icing
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.
½ tbsp powdered gelatin or 2 sheets gelatin
¼ cup (60g) heavy cream
5tbsp (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 your 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 (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.
You have two choices for Step 2, you can either have Dacquoise on the top and bottom of your log as in version A or you can have Dacquoise simply on the bottom of your log as in version B:
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 crème 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 crème 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.
1. Pipe one third of the Mousse component into the mold.
2. Take the crème 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.
3. Pipe second third of the Mousse component around and on top of the crème brulee insert.
4. 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.
5. Pipe the last third of the Mousse component on top of the Praline Insert.
6. Freeze for a few hours to set. Take out of the freezer.
7. 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.
8. Close with the Dacquoise.
Freeze until the next day.
If you are doing the assembly UPSIDE DOWN with TWO pieces of Dacquoise the order is:
3) Crème Brulee Insert
5) Praline/Crisp Insert
7) Ganache Insert
If you are doing the assembly UPSIDE DOWN with ONE piece of Dacquoise on the BOTTOM ONLY the order is:
2) Crème Brulee Insert
4) Praline/Crisp Insert
6) Ganache Insert
If you are doing the assembly RIGHT SIDE UP in a springform pan the order is:
2) Ganache Insert
4) Praline/Crisp Insert
6) Crème Brulee Insert
8 OPTIONAL) Dacquoise
THE NEXT DAY...
1. Unmold the cake/log/whatever and set on a wire rack over a shallow pan.
2. Cover the cake with the icing.
3. Let set. Return to the freezer.
4. 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...
5. Transfer to the refrigerator no longer than ½ hour before serving as it may start to melt quickly depending on the elements you chose.
