What You Need to Get Started

You can easily find all of the ingredients for a simple homemade lemon curd at your grocery store:

How to Make Easy Lemon Curd

The trick to lemon curd is a double boiler, which allows you to gently heat the lemon curd, so it doesn’t break or burn. If you don’t have a double boiler, you can place a heatproof bowl on top of a saucepan. The bowl should be large enough to sit above the water without touching it.

To get started, heat about an inch of water in the bottom pan of the double boiler and bring it to a boil. Once bubbling, lower the heat so it remains at a simmer. The steam from the water will then heat the top pot or bowl.

While the water is coming to a boil, you can zest and juice your lemons. Then combine all of the zest and juice into the top of your double boiler with the eggs and sugar. Whisk everything together to combine it, and then place on top of the simmering water.

Whisk the mixture gently but constantly to keep it moving, and check the temperature as it cooks. Lemon curd does not need a lot of heat to come together, but you will want to make sure it reaches a minimum of 170°F in order to pasteurize the eggs.

The mixture will also begin to thicken and become uniform as you stir. When it’s ready, turn off the heat. Add in the butter, which you will want to have cut into tablespoon-sized slices or even a little bit smaller to increase the surface area. This will help it melt faster.

Stir in the butter until it melts and is fully incorporated into the lemon mixture. Then transfer the lemon curd into a glass jar or bowl. Cover it with plastic wrap, with the plastic touching the surface of the curd. This will help prevent a film from forming on the top.

Chill the completed lemon curd in the fridge for at least four hours to let it thicken up. If possible, leave it there overnight, so you can be sure it is fully cooled throughout.

Once chilled, the lemon curd can be stored in the fridge for weeks, as long as it’s in a sealed container. It no longer needs the plastic wrap touching the surface after it has chilled the first time. For longer storage, you can also freeze lemon curd. Allow it to thaw in the fridge overnight before using it.
