What is Lemon Curd?
Lemon curd is a tart, sweet, creamy combination of tart and sweet. Sugar free lemon curd tops the single serve cheesecakes I sell in my keto bakery. It’s great as a filling for lemon cake or lemon cupcakes.

You can use it on biscuits, toast, cake or cupcake fillings and more. I top my sugar free cheesecakes with lemon curd for my keto bakery. (recipe coming).

Make it sugar free by substituting sugar with allulose or a sweetener like Swerve. Allulose does not crystalize and is great for these types of recipes, but erythritol (Swerve, Lakanto, etc.) will also work.
