Description

This is how to make lemon curd at home yourself. It is an absolute treat and so easy that once you make your own, you will never want to buy store-bought again. This curd is thick, tangy, creamy, and sweet. Try it on desserts from cakes, cupcakes, pies, tarts, macarons, ice creams, and more

Ingredients

▢ 4 Egg yolks (large)
▢ 2 tablespoon Cornstarch
▢ ¼ teaspoon Salt
▢ 1 tablespoon Lemon zest
▢ ¾ cup (180 ml) Lemon Juice
▢ ¾ cup (150 g) Sugar
▢ ½ cup (113 g) Butter unsalted, cold, cubed

Instructions

Use a double boiler or make your own - To make your own add an inch of water to the saucepan with a heatproof bowl on top. The water should not touch the top bowl.
Pro tip - we use a double-boiler to prevent the eggs from getting scrambled with direct heat.
Juice the lemons - Place lemons in the microwave for 10 seconds before you cut and squeeze this will make it easy. Warm the lemon juice for about 30 secs - set aside
Pro tip - warming the lemons will get the most juice out of it. But, do not make it too hot to handle.
In the top bowl of your double boiler - add yolks, salt, cornstarch, and sugar. Whisk until light and fluffy - sugar should almost melt. Gradually pour in the warm lemon juice and zest
Pro tip - Whipping the egg will prevent them from splitting when we add the lemon juice.
Now place the bowl on the double boiler. Continue to stir on medium-high heat. The mixture should cook with just the steam from the water in the saucepan below.
Pro tip - if you cook on low it will take forever to thicken. Since we are cooking on a double boiler you can keep the heat medium-high and stir continuously.
Continue to stir until it coats the back of your wooden spoon for about 10 to 12 minutes. Remove from heat.
Pro tip - You will notice the foam that was caused by whipping the egg mixture will slowly disappear. The mixture will start to thicken and be creamy rather than liquidy.
Gradually add cubes of butter one at a time. Make sure each piece is almost incorporated before adding the next. The mixture will continue to thicken as it cools.
Pro tip - the cool butter stops the cooking process and makes a smooth and glossy curd. Add the butter slowly but not too slow or the last of the butter won't incorporate in cooled curd.
Once all the butter has been incorporated, strain it through a mesh or a strainer to remove the zest. This will also give you a smooth creamy curd.
Pro tip- straining will remove the lemon zest and any egg fat that may have curdled.
Transfer to a clean, dry, sterilized mason jar and store in the fridge for up to 2 weeks. These make the perfect gifts during the holidays too.

Recipe Notes

Juice the lemons easily - a great way to exact as much juice from lemons is to microwave the fruits for a few seconds (10 seconds).
Warm the lemon juice - warming the lemon juice helps it incorporate into the egg yolks well.
Egg yolks / Whole eggs - I find that all egg yolks have a higher risk of curdling but the one whole egg does help stabilize it.
Whip eggs and sugar until light and fluffy - If you whip the eggs with sugar until the sugar almost dissolves it prevents the egg from curdling.
Do not let the curd boil - cooking on low will prevent the curd from curdling. If the curd boils, it will give you lemon-flavored scrambled eggs. So no matter how boring - cook on low heat for 10 to 15 mins.
If you find the curd steaming up - take it off the heat for a few seconds this will help stabilize it.
How to know if the curd is done? You can use a thermometer and check until the curd reaches 170 F., But I find the best test is taste. Once the curd is thick and coats the back of a wooden spoon, taste it. It should not have any taste of eggs or cornstarch. If necessary cook for 30 secs more.
Add butter slowly - this will help bring the temperature of the curd down slowly without curdling.

Storage

The curd is best stored in a mason or glass jar in the fridge.
The presence of eggs in lemon curd makes it a perishable filling so any item that has homemade lemon curd such as cakes and pie needs to be placed in the fridge.
Avoid keeping fruit curd or citrus fillings in metal containers as the lemon can react with the metal.
Egg yolks can react with metal such as aluminum and cause them to become green in color.
