After cooking, pass the lemon curd through a fine-mesh strainer twice to remove any cooked egg bits and achieve that luxuriously smooth, velvety consistency that defines premium curd.

Always zest your lemons before cutting them in half to juice, as it's nearly impossible to zest a halved lemon; this ensures you capture all the aromatic oils for maximum flavor.

Use a double boiler or bain-marie over medium-low heat to prevent scrambled eggs; stir constantly and keep the mixture between 160-170°F to achieve creamy curd without any grainy texture.

Add cold, cubed butter to the hot curd off the heat while stirring vigorously—this creates an emulsion that prevents separation and yields a silkier, more luxurious final product.

Warm your lemons in the microwave for 20 seconds before juicing to extract significantly more juice with fuller, brighter flavor compared to room-temperature fruit.
