Strain the finished curd through a fine-mesh sieve twice to remove any cooked egg bits or zest particles, ensuring luxuriously smooth texture every time.

Slowly drizzle hot mixture into beaten eggs while whisking constantly, rather than pouring all at once, to prevent curdling and achieve a creamy consistency.

Always zest your lemons before cutting and juicing them—once halved, the fruit becomes too slippery and you'll lose precious zest oils that add bright, complex flavor.

Stir in cold, cubed butter at the end of cooking while the mixture is still warm to create an emulsion that gives your curd a silky sheen and luxurious mouthfeel.

Press plastic wrap directly onto the curd's surface before refrigerating to prevent a skin from forming, and allow at least 4 hours for the curd to set to perfect spreading consistency.
