FAQs

What is lemon curd?

Lemon curd is a creamy, tangy spread made from lemon juice, sugar, eggs, and butter. It's used as a topping or filling for various desserts.

Can I use bottled lemon juice?

While fresh lemon juice is best for flavor, bottled lemon juice can be used in a pinch.

Why did my lemon curd curdle?

Curdling can happen if the mixture overheats. Microwave in intervals and stir between each to avoid this.

How do I know when the curd is done?

It's ready when it thickens enough to coat the back of a spoon and continues to thicken as it cools.

Can I double the recipe?

Yes, but be cautious with microwaving times. Larger amounts may need longer cooking and more stirring.

Is it necessary to strain the curd?

Straining removes zest and any cooked egg bits, creating a smoother texture. It's recommended but optional.

Can I make this on the stovetop?

Yes. Cook over low heat in a saucepan, stirring constantly until it thickens.

What can I use lemon curd for?

Use it as a spread, filling for cakes and tarts, or topping for yogurt, pancakes, and more.

How long does lemon curd last?

Stored properly in the refrigerator, it can last up to 3 weeks.

Can I use salted butter?

Yes, though it may slightly change the flavor. If using salted butter, reduce other salt in the recipe.
