Olive Oil Lemon Curd Recipes

Steps:

• Make the cake: Preheat the oven to 300˚ F. Coat two 8-inch round cake pans with cooking spray. Combine the sugar, 2 1/3 cups flour, the baking powder, salt and 2 egg yolks in a large bowl; beat with a mixer on medium-high speed until well mixed. Stream in 1 cup olive oil and mix about 30 seconds. Beat in the 3 whole eggs, one at a time. Stream in the milk and vanilla and mix until combined.
• In a separate bowl, combine the chopped rosemary, remaining 2 teaspoons olive oil and 3 teaspoons flour. Fold the rosemary mixture into the batter.
• Pour the batter into the cake pans. Bake until a toothpick inserted into the centers comes out clean, 20 to 30 minutes. Transfer to a rack and let cool completely in the pans.
• Make the lemon curd: In a small saucepan, combine 1/4 cup sugar, the egg yolk, lemon zest and juice, cornstarch and 1 tablespoon butter. Stir continuously with a rubber spatula until the mixture boils and thickens, about 1 minute. Transfer the lemon curd to a bowl and place a piece of plastic wrap directly on the surface to prevent a skin from forming. Refrigerate to cool.
• Make the buttercream: Set up a stand mixer with the whisk attachment. In a medium saucepan, heat the egg whites and remaining 1 cup sugar over medium heat until the mixture reaches 160˚ F and the sugar is dissolved. (You should not be able to feel any sugar granules and the mixture should be very warm, not hot, to the touch.)
• Pour the egg white mixture into the mixer bowl and whisk on medium-high speed until the meringue is three times its volume, holds firm peaks and has cooled to about 95˚ F, about 4 minutes. Beat in the remaining 4 sticks butter slowly, piece by piece, until smooth and blended. Beat in the salt and vanilla.
• Remove the lemon curd from the refrigerator and fold it into the buttercream until well combined.
• Assemble the cake: Transfer 1 cake layer to a cake plate. Spread some of the buttercream on top using an offset spatula. Top with the other cake layer. Cover the top and sides of the cake with a thin layer of buttercream (this is the crumb coat); refrigerate 15 to 20 minutes. Cover with the remaining buttercream.

Steps:

• Place the lemon juice, sugar, eggs, egg yolk, lemon zest and salt in a blender, and blend until smooth, about 30 seconds. With the motor still running, slowly pour in the oil until just combined.
• Fill a medium saucepan with about an inch of water and bring water to boil over high heat. Transfer lemon mixture to a metal mixing bowl that can nestle into top of the saucepan without touching the water. Reduce heat to medium-low and, using a potholder or towel to protect your hands, whisk constantly until the curd thickens and looks like mayonnaise, 6 to 10 minutes. Do not overcook. (If you have a double boiler, you can use that here instead of the pot and the bowl.)
• Remove bowl from the heat and inspect the curd. If you see hard bits of coagulated egg, strain the curd through a fine mesh sieve, pressing with a rubber spatula. (If it looks smooth, you can skip this step.) Transfer curd to a container and press a piece of plastic wrap against the surface to create an airtight seal. Let the curd cool to room temperature, then refrigerate until cold, at least 1 hour.

Steps:

• Heat oven to 325 degrees and line a 9-by-9-inch baking pan with enough parchment to hang over two of the sides (to be used as handles later to lift the bars out of the pan).
• To make the shortbread base, pulse together the flour, granulated sugar, confectioners' sugar, lemon zest and salt in a food processor, or whisk together in a large bowl. Add butter and pulse (or use two knives or your fingers) to cut the butter into the flour until a crumbly dough forms. Press dough into prepared pan and bake until shortbread is pale golden all over, 30 to 35 minutes.
• While the shortbread is baking, prepare the lemon curd: Grate 1/2 tablespoon zest from lemons and set aside. Squeeze lemons to yield 3/4 cup juice.
• In a small saucepan, whisk together lemon juice, sugar, eggs and yolks, cornstarch and fine sea salt over medium heat until boiling and thickened, 2 to 5 minutes. Make sure mixture comes to a boil and stays there for 30 seconds or so; you should see it thicken up before you take it off the heat. But once it boils do not cook for longer than 1 minute or you risk the curd thinning out again. Remove from heat and strain into a bowl. Whisk in butter, olive oil and lemon zest.
• When the shortbread is ready, take it out of the oven and carefully pour the lemon curd onto the shortbread base; return the pan to the oven. Bake until topping is just set, 10 to 15 minutes more. Allow to cool to room temperature, then refrigerate until cold before cutting into bars. Sprinkle with confectioners' sugar and flaky sea salt right before serving.
