Lemon curd: cream, not just sweetened juice

Useful to know

Lemon curd is a smooth mixture of lemon, sugar, eggs and butter. King Arthur’s recipe uses controlled heating followed by cooling. [1]

Its base differs from jam, where fruit and sugar are the main focus. Sour flavour does not make it suitable for arbitrary storage in a sealed jar. Follow the recipe’s cooling and storage directions. In a tart or cake, consider the consistency after resting as well as how the curd flows while warm.
