Molly O'Neill's Lemon Curd Recipe (2024)

FAQs

How do you know when lemon curd is done? ›

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.

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.

Does lemon curd taste eggy? 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.

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.

Usually the temperature of milk determines how well your curd will set. Too cold or too hot temperature can make the curd setting process tougher. Firstly boil your milk properly and switch off the flame. Once the boiled milk cools down to 20 per cent, then the milk is ready to be set.

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.

Protein is Key to Thickening. The more protein in milk, the thicker the yogurt. The casein (protein) clusters in milk thicken yogurt by unraveling and forming a three-dimensional mesh when exposed to the lactic acid created by culturing.

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.

Why did my lemon curd scramble? ›

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.

Follow the recipe exactly for best texture. If you use too many whole eggs, the egg white will cause foaming and the curd will end up foamy.

Shelf life

Plan to use canned lemon curd within 3–4 months.

Many lemon curd recipes call for 6+ Tablespoons of butter, though I think 4 Tablespoons provides richness while preserving a mouthwatering, puckery-lemon flavor. Feel free to use vegan butter if you need it. Vanilla extract: just a drizzle rounds out the flavor of the lemon curd and cuts out any sharp sourness.

Prepared lemon curd can be frozen for up to 1 year without quality changes when thawed. To thaw, move the container from the freezer to a refrigerator at 40°F or colder for 24 hours before intended use. After thawing, store in the refrigerator in a covered container and consume within 4 weeks.

Pro tips for making this recipe

You'll know the curd is ready when it noticeably thickens in consistency and coats the back of a wooden spoon.

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.

Set the tart in the oven for 20-22 minutes, until it's matte colored all over, the sides don't move when jiggled but there's a slight jiggle in the center of the tart. Chill first at room temperature, then set in the fridge to chill for 4-8 hours, or up to 2 days. Serve cold and store leftovers in the fridge.

The color of the lemon curd is depending on the egg yolks that you use, and if the yolks color is more orange than yellow, then your lemon curd will turn dark yellow- orange color and not bright yellow.
