Method
Cook and puree rhubarb
- Combine chopped fresh rhubarb and 1/2 cup sugar in a saucepan and cook over medium heat until very soft, about 8 minutes, stirring occasionally so it breaks down evenly.
- Puree the cooked rhubarb until smooth in a blender, then return the pink puree to the saucepan.
Thicken the curd
- Whisk in the remaining sugar, egg yolks, and lemon juice until smooth and uniform in color.
- Cook over medium-low heat, stirring constantly, until the mixture thickens and coats the back of a spoon, about 6-8 minutes, and looks glossy and smooth.
- Remove from heat and whisk in the butter cubes until completely melted and the curd is silky and smooth.
- Strain through a fine mesh sieve if desired for extra smoothness, using a spatula to press gently for a clean texture.
Chill and store
- Pour the curd into clean jars, cover, and refrigerate for at least 2 hours, until it firms up to a spreadable consistency.
- Store in the refrigerator for up to 2 weeks for best flavor and texture.
Notes
Pro tip: keep the heat at medium-low and stir constantly so the egg yolks thicken without scrambling. Refrigerate in sealed jars up to 2 weeks; freezing is not recommended because the curd texture can break after thawing. For a dairy-free swap, use a plant-based butter substitute formulated for baking/melting and expect a slightly softer set.
