How do you know when lemon curd is done cooking? ›

Dip a spoon into the curd then run your finger over the back of it. If it leaves a clean line in the curd, it's cooked enough and ready to cool. Curd will thicken up more once cooled completely. Spoon into a container, cover and refrigerate.

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!

Place over a saucepan of simmering water and cook, stirring constantly to prevent it from curdling, until the mixture becomes thick (like sour cream) and coats the back of a wooden spoon (165 degrees F) (74 degrees C).

Use Sufficient Egg Yolks

Lemon curd has traces of yellow in it naturally, but its striking golden colour comes from the yolks. Also, incorporating whole eggs is not preferred since the egg whites cause the lemon curd to become lighter.

The few reasons to why your lemon curd may not be setting properly are not having enough eggs in the curd, too much liquid/ lemon juice, not enough sugar, not cooked long enough, scrambled eggs, and sometimes too much butter.

While in a warm climate, the curd will take around 4 to 7 hours, while it will take a bit longer in winters. In a cool climate it can easily take around 8 to 10 hours. Make sure the temperature of the milk before setting the curd is warm enough during winters, otherwise the curd won't set properly.

Not using enough yolks

Additionally, using too many whites can cause your lemon curd to taste egg and sulfurous, which many people find unappetizing. The sulfur in the whites can also lead to an unpleasant smell, which you certainly don't want. The smell is worse in older eggs, so try to use fresh ones if possible.

Although lemon curd uses egg yolks and/or egg whites, the final product shouldn't taste eggy. If it does, it may mean that you've overcooked your eggs. In saying that, traditional lemon curd does have a distinct after taste which doesn't sit well with some.

If the milk does not set well, try again with fresh milk in different ways by increasing the culture, keeping it in a warmer place, adding your culture to warmer milk. Making good curd at home comes by experimenting & experience.

In a covered, airtight container for up to one week. It doesn't really freeze well. Lemon curd does contain eggs and dairy (butter), so I'd be ok leaving it out for the day if I plan on serving it, but anything overnight definitely would need to be refrigerated.

Why is my lemon curd grainy? ›

Why is my lemon curd grainy? One of the reasons curd becomes grainy is due to the temperature being too high, causing the cooking process to start before the curd is fully prepared. Egg proteins begin to coagulate at around 140°F (75°C).

Between the heat and whisking, lemon curd gets foamy while it's cooking. As the curd begins to thicken, the foam will start to settle down, and then the addition of the butter at the end of cooking eliminates the foam. So don't panic when you see foam, just keep whisking and cooking.

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.

There are majorly two reasons that curd turns sticky, firstly the bacteria culture used to make curd can impact the taste and texture. Secondly, if you keep the curd at a low temperature, it takes a lot of time to set as well as forms a slimy texture. This is because curd needs a slightly warm temperature to set.

To test if the curd is cooked properly, dip a spoon into the mixture then run your finger through the mixture on the back of the spoon. The line made by your finger should hold and remain clear, without any sign of the curd flowing back into the space.

If you make your lemon curd over too high a heat or don't stir it regularly as it cooks, you may find that it goes a little lumpy with flecks of cooked egg white in it. The easiest way to fix this is to give it a quick blitz in a blender (or using a stick blender) until it is smooth.
