In a saucepan, whisk together lemon juice, lemon zest, sugar, and egg yolks until smooth. Cook over medium-low heat, stirring constantly to prevent curdling, until the mixture thickens enough to coat the back of a spoon, approximately 6 to 8 minutes. Remove from heat and immediately stir in cubed butter until fully incorporated and smooth. For extra smoothness, strain through a fine sieve. Let cool to room temperature, then chill until set.
