In a large saucepan, combine the lemon juice, butter, and sugar. Heat over medium high heat until the butter melts and sugar dissolves.
Break the eggs into a medium (heat resistant) bowl and whisk them until well combined. Slowly add the lemon sugar mixture to the eggs, a few tablespoons at a time, stirring between additions. This prevents the eggs from curdling.
Return the mixture back to the saucepan and turn heat to medium-low. Whisk the curd constantly, alternating with using a silicone spatula to prevent the mixture from sticking to the bottom or sides of the pan.
Once the curd thickens enough to coat the back of a spoon, about 5 minutes, remove it from the heat.
Allow the curd to cool for 15 to 20 minutes, then add to a bowl, stirring before covering the surface with plastic wrap to prevent a skin from forming on top.
Let cool until just lukewarm, then refrigerate until set (about 2 hours).
Notes
To get the most juice out of your fresh lemons, roll them on a hard surface like a countertop for 5-10 seconds.
Recipe Variations:
Sweeter curd: Meyer lemons are naturally sweeter than regular lemons, but you can add a little honey or vanilla extract for extra depth.
Dairy-free version: Swap out the butter for coconut oil for a dairy-free alternative with a slightly tropical twist.
Extra tart flavor: If you love a sharper citrus kick, mix in a splash of regular lemon juice with your Meyer lemon juice.
Thicker curd: Simmer the curd a bit longer to evaporate more liquid or stir in an extra egg yolk for a richer consistency.
