Problem: My Lemon Curd is Too Runny

The curd wasn't cooked long enough to allow the egg to thicken, or not enough butter was added. How to fix it: To thicken runny lemon curd, put the curd back into your saucepan, place over the lowest possible heat, and stir constantly.

Trouble shooting: Most Lemon Curds are runny because they don't get cooked long enough, to 170 degrees F, to thicken the egg yolks – so cook on! If your curd isn't thickened after 10 minutes, or up to 15 if using a double boiler, then increase the temperature of the stove slightly – and don't stop whisking!

If your lemon curd hasn't thickened, it may not have been heated enough. It can take up to 30 minutes of constant stirring to cook lemon curd, especially if it's a large batch. Remember that curd will thicken more once cooled. If your cooled curd is not thick enough, you can reheat it to thicken.

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.

What happens if I over-cook lemon curd? 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.

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.

A metallic aftertaste is usually the consequence of the lemon curd coming into contact with a metal (especially while it's hot). This could be a metal whisk, a metal bowl, a metal (or metal-coated) saucepan, or a metal sieve.

Use Full Cream Milk

Rich, full cream milk is considered best for making curd because of its high fat content. It results in a thicker, creamier texture often preferred by many people. Additionally, the fat in full cream milk can help create more flavour with a smooth, velvety texture.

Simply crack an additional egg and separate the yolk from the egg white. Place the yolk in a small bowl. Gradually add a small amount of the curdled lemon curd to the bowl containing the additional egg yolk, which is essetnailly a stabilizer.

Should you refrigerate lemon curd? ›

Just be sure to put it in a tightly sealed glass or plastic container so it doesn't pick up any aromas from other things in your fridge. Fresh lemon curd will keep for one to two weeks when stored in the refrigerator in a sealed container.

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. After thawing, consume within 4 weeks.

I like to cook the curd in a stainless steel bowl placed over a saucepan of simmering water (a double boiler) as this helps prevent the eggs from curdling. That is, where you get little specks of cooked egg in the lemon curd.

Let's peel back the layers of this zesty enigma. It all comes down to chemistry. Lemon juice, a primary ingredient in lemon curd, is rich in citric acid. When this acid comes into contact with certain metals, notably copper or aluminum, a chemical reaction occurs.

Lemon curd thickens around 160-170˚F. Once you see it start bubbling, let it gently simmer for a few seconds then remove it from the heat at 175-180˚F on a thermometer. It should coat the back of a spoon without running when you pull your finger across the spoon.

The butter makes the lemon curd extra rich and creamy. And after you've chilled the lemon curd in the fridge for a while, the butter will firm up and make sure that the curd sets properly.

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.
