French Yule Log

picnik-collage12

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.

The French Yule Log was truly challenging for me because it was my first try. But the challenge was worth-while, I must say.  My family and I loved it so much,we have become true French dessert fans : ).On any given day, I would never even contemplate making such a dessert,but because I am a daring baker🙂, I MUST live up to my title.

I have to admit that I was a little  intimidated  by this recipe,  I must have read the recipe close to,  well, close to 500 times🙂

Day 1 – I prepared the almond dacquoise, crisp insert and the creme brulee.

Day 2 – I continued the process. I prepare the mousse, ganache insert.

Day 3-  I prepared the icing.

French Yule log Recipe:

Element #1 Dacquoise Biscuit (Almond Cake)

Ingredients:
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.

Vanilla Mousse
2/3 cup (160g) heavy cream (35% fat content)
2/3 cup (160g) whole milk
1 vanilla bean
4 medium-sized egg yolks
3 oz (6 Tbsp / 80g) granulated sugar
3 Tbsp (25g) cornstarch, sifted
4g / 2 tsp powdered gelatin or 2 sheets gelatin
1 cup (240g) whipping cream (35% fat content)

Make a pastry cream:
1.    Pour the milk and 2/3 cup cream into a saucepan. Split the vanilla bean in half, scrape the seeds from the vanilla bean halves into milk and put the vanilla bean in as well.
2.    Heat to boiling, then turn the heat off, cover and let infuse for at least 30 minutes. Then remove the vanilla bean.
3.    Beat the egg yolks with the sugar until white, thick and fluffy.
4.    Add the cornstarch, beating carefully to ensure that there are no lumps. While whisking vigorously, pour some of the milk into the yolk mixture to temper it.
5.    Put infused milk back on the stove on medium heat. Pour yolk mixture back into the milk while whisking vigorously. Keep whisking vigorously until mixture thickens considerably.
6.    As soon as the mixture starts to boil, leave on for only 2 more minutes. (The recipe says you should remove the vanilla bean at this time but in the interest of no one getting burned, that can be done after you take the pastry cream off the stove.)
7.    Once removed from the heat, cover the pastry cream by putting plastic film directly on the surface of the cream (this prevents it from forming a thick and unappetizing skin as it cools). Let cool at room temperature.
8.    Soften the gelatin in cold water and melt in a small saucepan with 1 tsp of water OR melt in the microwave for 1 second (do not boil). Whisking vigorously, pour the cooled pastry cream over it.
9.    Whip the 1 cup whipping cream until stiff and add gradually to the pastry cream (DO NOT WHISK). Blend delicately with a spatula (DO NOT WHISK).

Element #3 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.

Ingredients:
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 (if you have a plunging mixer use it). The chocolate should be smooth and shiny.

Element #4 Praline Feuillete (Crisp) Insert

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.

Coconut Crisp Insert

3.5 oz (100g) white chocolate
1 oz (1/3 cup/25g) shredded coconut
1 2/3 Tbsp (25g) unsalted butter
2.1 oz (60g) lace crepes or rice krispies or corn flakes or Special K

1.  Spread the coconut on a baking tray and bake for 5-10 minutes at 375°F (190°C) to toast (a different temperature might work better for you with your own oven).
2.  Melt the white chocolate and butter in a double boiler. Stir until smooth and add the toasted coconut.
3.  Add the coarsely crushed lace crepes. Mix quickly to thoroughly coat with the chocolate. 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
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.

Element #6 Dark Chocolate 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.

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.

(Decorate the cake as you wish)

Thank you, Hilda and Marion and Happy New Year to everyone!
