Lemon curd is a traditional English spread and dessert topping that dates back to the early 19th century. It originated as a lemon-flavored custard, initially made with lemon juice, sugar, and egg yolks, then strained through a cloth to separate the curd from the whey. Lemon curd became popular as an accompaniment to scones and tea cakes, especially during afternoon tea, a quintessential British tradition.

In the 20th century, lemon curd became widely available commercially, making it easier for people to enjoy without the need for homemade preparation. It also started to appear in cookbooks, further cementing its place in both everyday and special-occasion cooking. The development of home canning techniques allowed lemon curd to be stored for longer periods, contributing to its widespread use.

Over time, lemon curd has evolved into a smooth, thick spread, more akin to a preserve. It is commonly used as a filling for tarts, cakes, and pastries, and as a spread for toast and scones. The zesty, tangy flavour of lemon curd, combined with its rich, creamy texture, has made it a favourite in many parts of the world.

My Tips:

• Fresh lemon juice provides the best flavor. Avoid bottled lemon juice.
• Keep the heat moderate and stir constantly to prevent the eggs from curdling.
• Straining the curd ensures a silky-smooth consistency by removing any bits of cooked egg or zest.
• Experiment with adding herbs like thyme or rosemary for a sophisticated twist.
• Use natural sweeteners and dairy-free butter alternatives to create a healthier version.

Troubleshooting Guide:

Mixture starts to curdle

If the mixture starts to curdle, immediately remove it from heat and whisk vigorously. Strain through a fine mesh sieve to remove any lumps.

Thickening issue

If the curd isn’t thickening, ensure you are cooking it over medium-low heat and stirring constantly. It should reach a temperature of about 75°C to 80°C.
