Why didn't my lemon curd thicken enough? ›

Add a cornstarch slurry: First, ensure your curd is cooked to 170 degrees F and if it still hasn't thickened, whisk 1 teaspoon cornstarch with 1 tablespoon water until the cornstarch is completely dissolved.

I cook mine for about 2 minutes because I like thick lemon curd. Test the thickness by dipping the back of a spoon into your lemon curd and drag your finger across it. If it holds the shape without dripping off too quickly, it's done!

Lemon curd will last up to 2 weeks in the fridge, so it is great to make it in advance when you need it to fill cakes and pastries.

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.

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.

Don't be tempted to use bottled lemon juice of any kind as it'll be far too acidic and will ruin the flavor. You'll know the curd is ready when it noticeably thickens in consistency and coats the back of a wooden spoon. Keep the heat low, don't turn it up to quicken the process or the eggs will scramble.

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.

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.

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.

Can lemon curd sit out overnight? ›

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.

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.

Additionally, a sour or off smell is a good indicator that it has turned bad.

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.

Problem: The Curd is Chunky or Grainy

The curd was overcooked, or the uncooked ingredients sat too long and the acidity curdled the eggs.

Not heating the milk enough results in lacey/gooey/stringy Dahi. Using Low fat milk or skim milk may result in Dahi that's not firm enough. Use starter from a good quality Greek Yogurt that contains good bacteria strains. Be wary on ingredients like thickeners or any other additives.

Simply add a small amount of yogurt, like a spoonful, at a time. Stir your yogurt into the curry and keep adding a little more at a time until it reaches your desired thickness. This is great for Indian-style curries as a cream substitute.

I have used agar agar and/or tapioca starch. I prefer a combination of the two, but they must be heated, so, it's best to heat the milk with the thickeners, let them thicken, then let it cool to luke warm, then add the yogurt starter, or whatever yogurt culture you're using.

To fix it, remove it from heat and quickly transfer it to a blender or food processor. Blend on high speed until the mixture becomes smooth and creamy. Alternatively, you can strain the curd through a fine-mesh sieve to remove any lumps.
