Ça a l'air vraiment bon...

Ingredients

For the cake

• 300 g cream cheese (full fat; see end Notes)
• 200 ml heavy (whipping) cream (¾ cup + 4 tsp; or use whole milk)
• 6 large eggs (50 g each w/o shell) (10.6 oz, 300 g w/o shells)
• 60 g unsalted butter (plus 1 Tbsp to grease the pan and parchment paper)
• 60 g sugar (for the cream cheese mixture)
• 100 g sugar (for the egg whites)
• 80 g cake flour (weigh for accuracy; click the Metric button above for weights; or learn how to measure flour with a measuring cup; you can make homemade cake flour)
• 0.5 large lemon (for the zest + 2 Tbsp juice)

For the glaze

• 2 Tbsp apricot jam
• 2 tsp hot water

Instructions

To Prepare the Cake Pan

1. Use a 9-inch (23-cm) x 4 inch (10 cm) cake pan. Cut one circle of parchment paper 9 inches (23 cm) in diameter (or use a 9-inch round parchment cake liner) and one rectangular strip 4 x 30 inches (10 x 76 cm). Cut two straps 2 x 30 inches (5 x 76 cm) each to use to lift the baked cake from the pan.
2. Use 1 Tbsp unsalted butter to grease the cake pan and one side of the parchment paper circle and strip. You don‘t need to use all the butter.
3. Crisscross the two straps on the bottom of the pan to form an “X" and let the excess hang over the edges. Line the paper circle on the bottom and the strip on the sides, keeping the greased side touching the pan.

To Prepare the Oven and Double Boiler

1. Preheat the oven to 350ºF (180ºC). For a convection oven, reduce the temperature by 25ºF (15ºC).
   Note: You will be baking at 320ºF (160ºC), but we’ll preheat a bit higher because your oven will lose heat when you open it to place the cake pan inside.
2. Set a medium saucepan with 2 inches (5 cm) of water over high heat for the double boiler. Bring it to a simmer, then cover and reduce the heat to maintain a steady simmer.

To Separate the Eggs

1. Gather all the ingredients.
2. Separate 6 large eggs (50 g each w/o shell) into egg yolks and whites. Place the egg whites in the refrigerator until ready to use.

To Make the Batter

1. Add 300 g cream cheese, 60 g unsalted butter, 200 ml heavy (whipping) cream, and 60 g sugar to a large bowl and rest it on the saucepan above the simmering water.
2. Mash the cream cheese and butter with a silicone spatula until soft, then whisk the mixture until smooth and combined. Remove from the heat.
3. Add the egg yolks one at a time, whisking each yolk into the cream cheese mixture until fully incorporated before adding the next.
4. Sift 80 g cake flour into the batter with a fine-mesh strainer. Whisk until no dry streaks remain.
5. Pass the batter through the strainer into a clean large bowl.
6. Add the zest of 0.5 large lemon (outer yellow layer only, avoiding the white pith) and 2 Tbsp lemon juice and whisk to combine.

To Set Up the Hot Water Bath (Bain-Marie)

1. Place a large baking sheet inside the preheating oven and add hot water until it is ½ inch deep (halfway up the sides). Close the oven door.

To Beat and Fold In the Meringue

1. Add the cold egg whites to the cold, dry, and clean stand mixer bowl. Start on low (Speed 2) for 30 seconds to break down the egg whites and loosen their structure. Increase to medium (Speed 4) for 2 minutes until they become opaque, foamy, and bubbly. Slowly add 100 g sugar, one-third at a time, while mixing.
2. Increase the speed to medium high (Speed 6–8) and beat the egg whites to firm peaks. Stop the mixer to check: When you lift the whisk upright, the egg whites should cling and hold their shape with the tip folding back on itself.
3. Add one-third of this meringue to the cream cheese mixture and whisk until incorporated. Fold in another one-third of the egg whites.
4. Pour the cream cheese mixture into the mixer bowl with the last of the meringue. Fold until just combined.
5. To minimize air pockets, pour the batter into one spot in the cake pan in a steady stream. Tap the pan on the counter a few times to release any trapped air.

To Bake the Cheesecake

1. Quickly place the cake pan on the baking sheet with the hot water bath.
2. Reduce oven to 320ºF (160ºC)—295ºF (145ºC) for convection—and bake for 70–75 minutes.
3. Reduce oven to 300ºF (150ºC)—275ºF (135ºC) for convection—and bake for 10 more minutes, until the top is golden brown. [Don't remove the cake!]

To Cool and Chill

1. Turn off the heat and leave the cake inside the oven with the door slightly ajar for 15–20 minutes.
2. Remove the cake from the oven. Lift the cheesecake from the cake pan using the two parchment straps—an extra set of hands helps here.
3. Place the cake on a platter. Peel away the parchment paper from the sides (leave the bottom paper). Mix 2 Tbsp apricot jam and 2 tsp hot water in a small bowl and gently brush it on top of the cake. Cool to room temperature, then chill in the refrigerator for at least 4–6 hours or overnight.
