Ingredients
- 3 large eggs
- 1 egg yolk
- 2/3 cup granulated sugar
- 1/2 cup fresh lemon juice
- 1 tablespoon finely grated lemon zest
- 6 tablespoons unsalted butter cubed
Instructions
- Pour about 2 inches of water into the bottom pot of your double boiler and heat on high. Once it reaches a boil, lower the heat to maintain a simmer.
- In a medium bowl, whisk together eggs, yolk, granulated sugar, lemon juice, and lemon zest until smooth.
- Transfer the mixture to the top of the double boiler and cook the curd, stirring constantly, until the mixture thickens and coats the back of a spoon, about 10-15 minutes.
- Remove from heat and stir in cubed unsalted butter until melted and the mixture is smooth.
- Strain the lemon curd through a fine mesh sieve into a bowl. Place plastic wrap directly on the surface of the lemon curd to prevent a skin from forming, and refrigerate until completely cooled.
