Step 1

In a small saucepan whisk together the egg yolks, sugar, lemon juice and lemon zest.

Step 2

Then on low-medium heat, cook the lemon mixture until it boils lightly then thickens, making sure to whisk constantly so there are no lumps. This step should only take about 5 minutes.

Step 3

Remove the lemon mixture from the heat and stir in the butter until it is melted and thoroughly mixed in. The curd should look creamy.

Step 4

Set aside to cool. Or you can use it right away…warm lemon curd is delicious too!
