Ingredients :
- 3 large eggs
- 1 large egg yolk
- 2 1/4 cups sugar
- 1/2 cup butter cubed
- 1 1/2 teaspoons lime zest
- 3 ounces lime juice
Directions :
- Bring a saucepan of water to a gentle simmer and set a glass or metal bowl over the top to create a double boiler. In the bowl, whisk together eggs, yolks, sugar, butter, lime zest, and lime juice.
- Cook over the simmering water, stirring frequently, until very thick, about 20 to 25 minutes (the curd must reach 170 degrees on a thermometer to thicken). Strain through a fine-mesh strainer or cheesecloth, then cover and chill completely.
