How to make Easy Lemon Curd Recipe - Crazy for Crust (2024)

FAQs

How do you stiffen lemon curd? ›

If your curd has been cooked to 170 degrees and it still hasn't thickened, then make a slurry by whisking 1 teaspoon cornstarch with 1 tablespoon water until the cornstarch is completely dissolved.

If your cooled curd is not thick enough, you can reheat it to thicken. Put it over a low heat, stirring constantly. Ensure it coats the back of a spoon before taking it off the heat.

Avoid Over-cooking The Curd

Your lemon curd could get chunky and grainy if you let it overcook. One thing you should remember while making lemon curd is that you should never let it reach a point where it starts boiling. The ideal temperature for lemon curd is 170 degrees Fahrenheit, and it shouldn't cross that.

But WHY did the Lemon Curd scramble? I learned that day, based on the scientific fact that eggs do not curdle when cooked in the presence of starch, and because Lemon Curd has no starch (such as flour or cornstarch), it will curdle when the eggs get too hot.

CURDS THAT WON'T COME TOGETHER

This is often caused by improper temperatures; either you used UHT (Ultra High Temperature) pasteurized milk or your curds got too hot when you were preparing for the stretching stage, or they didn't get hot enough. The temperature of the curds before stretching should be 160° to 170°F.

Overcooking will cause proteins to bond too tightly, squeezing water out from between them and giving them a rubbery, lumpy texture. If you over-heat the lemon curd, the egg proteins can coagulate and you will see little bits of cooked egg.

Either the mixture wasn't constantly stirred and the egg yolks got cooked on the bottom of the pot. Or, the entire mixture was cooked too much and reached close to the boiling point. You can try to strain it out, but it might have an eggy aftertaste. My lemon curd is too sour.

If you just place all the ingredients in a saucepan without beating the butter and sugar with the eggs first, the curd tends to taste eggy. Add the lemon juice and tablespoons of lemon zest and mix.

If your pie filling is runny, add in one additional tablespoon of cornstarch to the lemon filling, and stir over medium heat. It should thicken in 1 to 2 minutes.

There are a few reasons why your lemon curd may taste metallic. The most common reason is usual due to using aluminum or metal bowls. The acid in lemon juice tends to react with metal, and sometimes eggs can react with aluminum.

Why did my lemon curd turn green? ›

If your lemon curd turned green, it likely had a reaction to something metal. Avoid using a copper or aluminum pan as those will react with the lemon juice and cause the discoloration in the lemon curd, and could even cause a slightly metallic aftertaste.

Shelf life

For best quality, store in a cool, dark place (away from light). Plan to use canned lemon curd within 3–4 months. Browning and/or separation may occur with longer storage; discard any time these changes are observed.

EDIT: I managed to fix it by reheating it, letting it get somewhat smooth, straining it, adding lemon juice, and then stirring more. I did it with one orange so I couldn't just start over again. I'm thankful for the advice though! The curd is now a beautiful orange, a bit thick and sweet, but really good!!

Why is my lemon curd not thickening? Make sure to cook the curd until thickened and bubbling. Stir it frequently with a rubber spatula or whisk to make sure it doesn't get lumpy. Once it's cooked, add cold butter and stir until it melts and becomes smooth.

Remove from heat and pass through a mesh strainer set over a bowl to remove the zest and any egg clumps. Place plastic wrap directly on top of the curd and let set in the fridge for at least 30 minutes before serving. Store in the fridge for 1-2 weeks.

Refrigeration is an important part as it helps to make the Dahi slightly firmer.

Shelf Life: Prepared lemon curd can be frozen for up to 1 year without quality changes when thawed. To thaw, place container in a refrigerator at 40°F or lower for 24 hours before intended use.

Once the tart is out of the oven, it is imperative that you allow it to cool completely in its pan before removing it. Neglecting to do so, as Zestful Kitchen explains, will result in cracking as the tart is still too warm at this stage to have set completely.
