Olive Oil Lemon Curd

Step 1

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.

Step 2

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.)

Step 3

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.
