Classic Citrus Curd
This is a fundamental technique for turning juice into a dense, bright spread. Once you master the temperature control of the stovetop, you can swap the citrus to suit whatever is in your bowl.
Control the heat to avoid scrambled eggs.
Keep your heat low and stay at the stove; curd breaks quickly if the eggs get too hot before the emulsion sets.

What goes in.
- 1/2 cupfresh citrus juice (lemon, lime, or grapefruit)
- 1 tbspfinely grated citrus zest
- 3/4 cupgranulated sugar
- 3large eggs
- 1large egg yolk
- 6 tbspunsalted butter, cubed and softened
Indirect gentle heating
Placing your bowl over a pan of simmering water prevents direct contact with the burner, allowing the eggs to thicken slowly without curdling.
The method.
Prepare the water bath
Fill your saucepan with an inch of water and bring it to a simmer over medium heat.
Whisk the base
In the mixing bowl, whisk the sugar, eggs, yolk, juice, and zest until combined. Place the bowl over the simmering water.
Thicken the mixture
Whisk constantly for 8 to 10 minutes. Stop when the curd thickens enough to hold a clean line when you run your finger across the back of a coated spoon.
Mount the butter
Remove the bowl from the heat. Whisk in the cubed butter one piece at a time until the curd is glossy and smooth.
Strain and chill
Pour the curd through a fine mesh strainer to catch any stray bits of cooked egg. Press a piece of plastic wrap directly onto the surface and refrigerate until cold.
Other turns to take.
Blood Orange
Replace the lemon juice with blood orange juice; reduce the sugar by one tablespoon to maintain the tart profile.
Meyer Lemon
Use Meyer lemon juice for a floral, less acidic finish; increase the zest to ensure the brightness comes through.
When it doesn't go to plan.
Use a glass or stainless steel bowl; avoid reactive metals like aluminum, which can give the curd a metallic taste.
If you see small yellow bits in the mixture, keep whisking off the heat; the residual heat of the butter often incorporates minor lumps.
Pressing plastic wrap against the surface prevents a skin from forming while the curd cools.
The ones that keep coming up.
Why did my curd turn out runny?
The curd was likely not cooked long enough. If it is fully cold and still loose, it did not reach the necessary temperature to set the egg proteins.
How long will this stay fresh?
Keep it in a sealed jar in the refrigerator for up to one week.
