• Make-Ahead

Ingredients

1. 2/3 cup sugar
2. 2 tablespoons finely grated lemon zest (4 lemons)
3. 2 tablespoons finely grated lime zest (6 limes)
4. 4 large eggs
5. 3 large egg yolks
6. 1/4 cup plus 2 tablespoons fresh orange juice
7. 1/4 cup plus 2 tablespoons fresh lime juice
8. 6 tablespoons unsalted butter, cut into pieces and softened

Directions

1. In a food processor, combine the sugar with the lemon zest and lime zest. Pulse 10 times until the sugar becomes light green.
2. In a medium heatproof bowl, whisk the eggs with the egg yolks, citrus sugar and orange and lime juices. Set the bowl over but not in a pan of simmering water and cook, stirring constantly with a wooden spoon, until thickened, about 10 minutes.
3. Remove the bowl from the heat and whisk in the butter, a few pieces at a time, until fully incorporated. Press the curd through a fine strainer set over a small bowl to remove any zest or scrambled egg. Press a piece of plastic wrap directly on the curd and refrigerate until chilled, at least 1 hour.

Make Ahead

The lemon curd can be refrigerated for up to 1 day.
