3.9 from 66 reviews

This easy blueberry curd is a luscious, tangy-sweet spread made from fresh blueberries, lemon, eggs, sugar, and butter. Perfect for spreading on toast, dolloping on yogurt, or using as a filling in desserts, this curd combines vibrant fruity flavors with a creamy, smooth texture. The double boiler cooking method ensures the eggs gently cook to create a silky custard without curdling, resulting in a homemade treat that’s both versatile and delicious.

  • Total Time: 30 minutes
  • Yield: 2 servings

Ingredients

Blueberry-Lemon Base

  • 1 cup fresh blueberries (or frozen)
  • Zest and juice of 1 lemon

Curd Mixture

  • 2 whole eggs
  • 2 egg yolks
  • 1 cup granulated sugar
  • A pinch of fine sea salt

Finishing

  • 1/2 cup unsalted butter (cut into small cubes)

Instructions

  1. Prepare the Blueberry-Lemon Base: In a saucepan over medium heat, combine the blueberries and lemon juice. Cook for 5-7 minutes, stirring occasionally, until the blueberries burst and release their juices.
  2. Strain the Mixture: Pour the cooked blueberries through a fine-mesh sieve set over a bowl. Use the back of a spoon to press the fruit and extract as much juice as possible. Stir in the lemon zest with the extracted juice and set aside.
  3. Prepare Egg Mixture: In a heat-proof bowl, whisk together the whole eggs, egg yolks, and granulated sugar until the mixture is smooth and evenly blended.
  4. Combine with Blueberry Base: Gradually whisk the blueberry-lemon juice mixture into the egg and sugar mixture until fully combined.
  5. Cook the Curd: Place the bowl over a pot of simmering water to create a double boiler. Add a pinch of fine sea salt. Stir the mixture constantly with a wooden spoon or heat-resistant silicone spatula for 10-15 minutes until it thickens and coats the back of the spoon.
  6. Add Butter: Remove the bowl from heat. Add the butter cubes one at a time, stirring after each addition until the butter is fully melted and the curd is smooth and glossy.
  7. Strain Again: For an ultra-smooth texture, strain the curd through a fine-mesh sieve into your desired storage container or jar.
  8. Cool and Store: Allow the curd to cool to room temperature. Place a sheet of plastic wrap directly on the surface to prevent a skin from forming. Seal the container and refrigerate for up to one week.

Notes

  • Use fresh or frozen blueberries; just thaw frozen if using.
  • Cooking the curd over a double boiler prevents overheating and curdling of eggs.
  • Pressing the cooked blueberries helps maximize flavor extraction.
  • Adding plastic wrap directly on the curd surface prevents skin formation.
  • Keep refrigerated and consume within one week for best freshness.
