Method
Soften and puree the rhubarb
- Combine rhubarb and 1/2 cup sugar in a saucepan and cook until very soft, about 8 minutes.
- Puree the softened rhubarb in a blender until smooth, then return it to the saucepan.
Thicken the curd
- Whisk in the remaining sugar, egg yolks, and lemon juice until fully combined.
- Cook over medium-low heat, stirring constantly, until the mixture thickens and coats the back of a spoon, about 6-8 minutes, and appears glossy and smooth.
Finish and chill
- Remove from the heat and whisk in the butter cubes until completely melted and smooth.
- Strain through a fine mesh sieve if desired for extra smoothness, using a gentle push to keep it silky.
- Pour the curd into clean jars, cover, and refrigerate for at least 2 hours until set and spoonable.
Notes
For the smoothest texture, keep the heat at medium-low and stir constantly while thickening so the egg yolks don’t scramble. Refrigerate in covered jars for up to 2 weeks; freezing is not recommended because the curd may become grainy. Dietary swap: use plant-based butter for a dairy-free version, noting the texture may be slightly softer.
