Zest one lemon and add to the sugar. Rub the zest with the sugar to release the oils. This step will add a lot of lemon flavor to the curd.
Zest of 1 lemon, ½ cup (105g) sugar
Add the zest and sugar mixture to a medium saucepan along with the lemon juice, eggs, and egg yolk. Whisk together until combined.
½ cup (120ml) fresh lemon juice, 2 large eggs, 1 egg yolk
Cook over low heat, whisking constantly just until the mixture starts to thicken. Immediately remove from the heat and stir in the butter until melted. Pour through a mesh strainer or sieve. This step will remove the zest along with any little chunks that may have formed while cooking, ensuring a smooth curd.
3 tablespoons butter
Pour into an airtight container and store in the refrigerator for up to 2 weeks.
Notes
FREEZER-FRIENDLY: Freeze in a freezer-safe container for up to 4 months.
Do not use bottled lemon juice.
Use salted butter if desired. Adds a nice touch!
