Citrus Curd
There is no middle ground with citrus curd; it demands your full attention at the stove. Once you master the rhythm of tempering the eggs, you have a foundation that works just as well for lemons as it does for limes, blood oranges, or grapefruit.
Temperature control is your primary tool
Curd will scramble if the heat is too high, so keep a whisk in your hand and the flame at its lowest setting. Avoid aluminum pans, as the citrus acid will leave a metallic taste.

What goes in.
- 1/2 cupfresh citrus juice (strained)
- 1 tbspcitrus zest
- 3/4 cupgranulated sugar
- 3large eggs
- 6 tbspunsalted butter, cubed and cold
Gradual Heat Integration
Slowly pour a small stream of the warm juice mixture into the beaten eggs while whisking constantly. This brings the egg temperature up safely before you expose them to direct heat.
The method.
Heat the base
Combine juice, zest, and half the sugar in the saucepan over medium-low. Heat until the sugar dissolves and the liquid begins to steam.
Temper the eggs
Whisk eggs and the remaining sugar in a separate bowl. Slowly drizzle in the hot juice while whisking the eggs constantly.
Thicken
Pour the mixture back into the saucepan. Cook over low heat, stirring constantly with a spatula, until the curd thickens enough to hold a clean path when you run your finger across the back of a coated spoon.
Finish and strain
Remove from heat immediately. Stir in the cold butter one cube at a time until emulsified. Pour through a fine-mesh sieve into a jar to catch any bits of cooked egg.
Set
Press a piece of plastic wrap directly onto the surface to prevent a skin from forming. Chill in the refrigerator for at least two hours.
Other turns to take.
Mixed Citrus
Combine blood orange and lime for a more complex, less acidic profile.
Herbal Infusion
Steep a sprig of fresh thyme or basil in the juice while heating, then remove before adding the eggs.
When it doesn't go to plan.
If you see small bits of egg after cooking, do not skip the straining step; it is the only way to get a perfectly smooth texture.
Use a glass jar for storage, as plastic can retain the flavor of the citrus.
If the curd feels thin, keep cooking for another minute, but remove it immediately if you see steam bubbles popping—that means it is boiling and about to break.
The ones that keep coming up.
Can I use bottled juice?
Avoid it. Bottled juice often contains preservatives that alter the flavor and prevent the curd from setting correctly.
How long does it stay fresh?
Kept in an airtight jar in the refrigerator, it remains good for up to two weeks.
