Ingredients

  • 150 g granulated sugar
  • 3 large eggs
  • 150 ml fresh lemon juice
  • zest of 2 lemons
  • 100 g unsalted butter, cubed

Steps

  1. In a mixing bowl, whisk together the granulated sugar and eggs until pale and fluffy, about 2 minutes.

  2. Stir in the fresh lemon juice and lemon zest, then transfer the mixture to a saucepan.

  3. Over medium-low heat, cook the mixture, stirring constantly, until it thickens and coats the back of a spoon, about 10 minutes. Do not let it boil.

  4. Once thickened, remove from heat and whisk in the cubed butter until fully melted and incorporated.

  5. Strain the lemon curd through a fine-mesh sieve into a clean bowl to remove any lumps.

  6. Allow the lemon curd to cool to room temperature before covering and refrigerating.

Why this works

The key to a smooth lemon curd lies in gentle cooking and continuous stirring. As you heat the mixture of eggs, sugar, and lemon juice, the proteins in the eggs coagulate, thickening the curd. If the temperature is too high, the eggs can scramble, resulting in a lumpy texture. If it breaks and appears curdled, immediately remove it from the heat and whisk vigorously to bring it back together. Straining the curd ensures a silky finish, removing any coagulated bits. The addition of butter not only enriches the flavor but also adds creaminess, creating a delightful mouthfeel. This lemon curd can be used as a filling for tarts or as a topping for desserts like pavlova or cheesecake, making it a versatile component in your dessert repertoire.
