Please Meet Gâteau St Honoré

I’m sure you’ve noticed through my posts that I entertain quite a bit.  I love cooking, baking and having friends over – it’s sort of my ‘thing’.  The tough part is being creative with my menus so that friends who visit often don’t have the same meal multiple times.  That’s why I’ve relied on my friend Lisa to make suggestions based on the blogs she visits or recipes she finds interesting.  Two weeks ago, she shared a recipe for a Gâteau St-Honoré she saw in Bon Appétit magazine and suggested I make it for a dinner party I hosted last weekend.  Little did I know how much work it would take to put my own spin on this very traditional recipe that I grew to enjoy with my Grandma at a local French bistro when I was a little girl.

Although I felt the presence of St Honoré, the patron saint of French pastry bakers (pâtissiers), with me as I baked this cake for 7 hours, I’m not sure I’d recommend novice bakers attempt this recipe, but it’s darn tasty if you put in the effort.

Pastry Base Ingredients:

• 2 sheets of frozen puff pastry from a 17 ¼-ounce box, thawed
• 2 Tbsp. all-purpose flour for dusting when rolling out the pastry

Choux (Cream Puffs) Ingredients:

• 1 cup whole milk
• 5 Tbsp. butter
• 1 tsp. granulated sugar
• ½ tsp. coarse salt
• I cup all-purpose flour
• 4 large eggs

Crème Pâtissière (Pastry Cream) Ingredients:

• 3 egg yolks
• ¼ cup granulated sugar
• 3 Tbsp. all-purpose flour
• 1 cup whole milk
• ¼ heavy cream
• 1 tsp. pure vanilla extract

Salted Caramel Mousseline Ingredients:

• 9 Tbsp. granulated sugar
• 1/8 tsp. cream of tartar
• ¼ cup heavy cream
• 2/3 of the Creme Pâtissière recipe above, chilled
• 2 sticks (1 cup) butter, softened
• ½ tsp. coarse salt
• ½ tsp. pure vanilla extract

Caramel Ingredients:

• ½ cup granulated sugar
• ¼ cup cold water

Pastry Base Directions:

1. Preheat oven to 375 degrees.
2. Spray an unrimmed baking sheet with cooking spray.  Place a piece of parchment paper on the baking sheet, ensuring it adheres to the cooking spray.
3. Unfold a puff pastry sheet on a floured work space.  Unfold the second pastry sheet and place directly on top of the first to create a double layer of pastry.  Using a rolling pin, lightly roll the pastry to enlarge the rectangular sheet by 2 inches in each direction.
4. Using a 10-inch cake pan or a paper guide, cut the pastry using a sharp knife into a 10” circle.  Place the circle on the prepared baking sheet and bake until golden brown, about 30 minutes.  Allow to cool completely on a wire rack.  Can be made the day before if stored in a sealed container at room temperature.

Choux Directions:

1. Preheat oven to 375 degree.
2. Spray an unrimmed baking sheet with cooking spray.  Place a piece of parchment paper on the baking sheet, ensuring it adheres to the cooking spray.
3. In a heavy, medium saucepan, bring the milk, butter, sugar and salt to a boil over medium-high heat.  Remove from heat and add the flour.  Stir with a wooden spoon to combine well.  Return the pan to the stove over medium heat and stir briskly until the dough pulls apart from the sides of the pan and forms a ball, about 2 minutes.
4. Transfer the dough to a stand mixer fitted with a paddle attachment.  Turn the mixer to medium speed, add eggs, one at a time, until well incorporated.
5. Add the dough to a pastry bag fitted with #2 tip.  Pipe 1” rounds on the parchment-lined baking sheet – should yield 25-30 rounds.  Dampen fingertips and smooth down the pointy tops of the rounds.
6. Bake for 20 minutes.  Lower oven temperature to 325 degrees and bake for an additional 15-20, or until choux are golden brown.  Remove from the oven and let stand on baking sheet for 2 minutes.  Remove the choux from the sheet and poke a small hole on the bottom of each one to let steam escape.  Let cool completely with bottom sides up.  Can be made up to 2 months ahead of time if stored in a sealed container in the freezer.

Crème Pâtissière Directions:

1. In a medium bowl, whisk together the eggs, sugar and flour until well combined.
2. In a heavy, medium saucepan, scald the milk, cream and vanilla.  Add a couple of ladleful of the hot liquid to the egg mixture and whisk to fully incorporate.  Add the egg mixture to the remaining hot cream mixture in the pan and whisk vigorously for 3-4 minutes until thickened.
3. Pour 1/3 of the crème in a small bowl and 2/3 of the crème in a medium bowl, press a sheet of plastic wrap on each of the crème’s surfaces and refrigerate until completely cool.

Salted Caramel Mousseline Directions:

1. Stir 2 tablespoons of water, the sugar, and the cream of tartar in a heavy, medium saucepan over medium-low heat until sugar dissolves.  Increase heat to medium-high and boil without stirring, occasionally swirling pan and brushing down sides with a wet pastry brush, until a deep amber color forms, about 7 minutes.
2. Remove the caramel from the heat and gradually add cream (mixture will bubble vigorously). Stir until any caramel bits dissolve and mixture is smooth.  Let cool.
3. In a stand mixer fitted with a whisk attachment, beat the chilled 2/3 of Crème Pâtissière and the cooled caramel sauce at medium speed.  Gradually add butter, 1 tablespoon at a time, beating until fully incorporated between additions.  Add salt and vanilla then chill until ready to use.

Caramel Directions:

1. Place the sugar and water in a heavy, small saucepan and stir with a wooden spoon over a medium-low heat until the sugar dissolves. Once dissolved, increase heat to medium-high and boil without stirring, occasionally swirling pan and brushing down sides with a wet pastry brush, until a light to medium golden color forms, about 5 minutes.  Remove from heat and use within 5 minutes.

To assemble:

For the choux:  Spoon the remaining 1/3 of the Crème Pâtissière into a pastry bag fitted with a #2 plain tip and pipe a small amount into 12 of the choux from the hole in the bottom of each.  Using tongs, carefully dip the tops of the 12 choux into the warm caramel to form a glaze.  Place caramel-coated puffs on a baking sheet coated with cooking spray and allow caramel to set.  Dip the tines of a small fork into any remaining caramel and drizzle 4-5 lattice-style shapes onto a baking sheet coated in cooking spray to use for decoration later.

For the base (to be done no more than 3-4 hours prior to serving):  Using a serrated knife, cut the puff pastry base horizontally into two circles.  Place one of the circles on a serving plate and spread 1/3 of the caramel Mousseline over it.  Top with the second pastry circle then another 1/3 of the Mousseline.

Final decorations:  Add the 12 caramel-coated choux to the top pastry circle in a circular pattern.  Add remaining Mousseline to a pastry bag fitted with a #2 plain tip and pipe small rosettes between each choux to fill any gaps on top of the cake.  Add hardened caramel decorations to the top of the cake.  Refrigerate cake until ready to serve.

Serves 8.

Notes:  Many components of the cake can be made in advance, so take advantage of that.  Final assembly should not be done prior to 3-4 hours before serving or the pastry will become soggy.  To save time and efforts, you could easily skip the Mousseline and just use Crème Pâtissière to make the cake (in the choux and to top pastry circles).  Remaining, unfilled choux can be used as profiteroles by cutting each choux tops, filling with ice cream and topping with chocolate sauce.
