Can I still use lemon curd if it’s past its expiration date?
If lemon curd is past its expiration date, it’s best to err on the side of caution and discard it. Lemon curd is a dairy-based product, and as such, it can spoil if not stored properly.

How can I extend the shelf life of lemon curd?
To extend the shelf life of lemon curd, it’s best to store it in the refrigerator at a temperature of 40°F (4°C) or below. Lemon curd can be stored in an airtight container in the refrigerator for up to a week. You can also freeze lemon curd for longer-term storage. To freeze, simply scoop the lemon curd into an airtight container or freezer bag and store in the freezer at 0°F (-18°C) or below.

What are some common mistakes to avoid when making lemon curd?
One common mistake to avoid when making lemon curd is not cooking the mixture long enough. Lemon curd needs to be cooked until it thickens and coats the back of a spoon. If the mixture is not cooked long enough, it may not set properly and can be too runny. Another common mistake is not using room temperature eggs. Cold eggs can cause the mixture to curdle, resulting in a grainy texture.
To avoid these mistakes, make sure to cook the lemon curd mixture over low heat, stirring constantly, until it thickens and coats the back of a spoon. Also, make sure to use room temperature eggs and butter to ensure a smooth and creamy texture.
Can I make lemon curd with other types of citrus fruits?
Yes, you can make lemon curd with other types of citrus fruits, such as limes, oranges, or grapefruits. Each type of citrus fruit will give the lemon curd a unique flavor and texture. For example, lime curd will have a more intense and tart flavor than lemon curd, while orange curd will have a sweeter and more mellow flavor.
When making lemon curd with other types of citrus fruits, keep in mind that the flavor and texture may be slightly different. You may need to adjust the amount of sugar or citrus juice to balance out the flavor. Also, some citrus fruits, such as grapefruits, may have a more bitter flavor than lemons, so you may need to add more sugar to balance out the flavor.
