Sweet & tangy homemade lemon curd is perfect for cakes, tarts, or by the spoonful! Easy recipe, simple ingredients and so much better than store-bought!
First, zest one lemon and set zest aside. Squeeze 3 large lemons, including the one you zested, enough to make ½ cup lemon juice. Strain out seeds and pulp.
Whisk eggs, sugar, lemon zest and salt in a medium saucepan. Whisk briskly until the mixture is frothy and lighter in color.
Add lemon juice and whisk until combined.
Add the butter cubes to the lemon mixture.
Place on the stove over low to medium low heat and whisk constantly until the mixture thickens. This usually takes 9-12 minutes. Use a digital thermometer to take the guess work out. It should read between 160-170°F for the proper thickening where it coats the back of a spoon.
Remove from heat and strain through a strainer into a glass or ceramic bowl. Stir with a whisk to make the process go a little faster.
Stir in vanilla extract then cover the bowl with plastic wrap. Make sure the plastic wrap sits on the top of the lemon curd to avoid a skin developing on the top of the curd.
Let it sit for about 30 minutes so that the mixture comes to room temperature. Pour into a jar with a tight fitting lid to store or into individual dishes if serving as dessert.
Chill for 2 hours before using.
Notes
STORE/FREEZETo Store: Transfer the cooled curd to an airtight container in the refrigerator. Note that it keeps best in glass because a metal container can give it a metallic taste. It will last up to 2 weeks.To Freeze: Transfer the cooled curd to a freezer-safe container, leaving ½-inch of room at the top because it will expand when freezing. Freeze for up to 3 months. Thaw in the fridge overnight.
