ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

1 cup fresh blueberries, or frozen
Zest and juice of 1 lemon
2 whole eggs
2 egg yolks
1 cup granulated sugar
½ cup unsalted butter, cut into small cubes
A pinch of fine sea salt

directions

In a saucepan over medium heat, cook blueberries with lemon juice until the berries burst and release their juices, about 5–7 minutes.
Strain the mixture through a fine-mesh sieve into a bowl, pressing to extract as much juice as possible. Stir in lemon zest and set aside.
In a heatproof bowl, whisk together whole eggs, egg yolks, and sugar until smooth.
Slowly whisk the blueberry-lemon juice into the egg mixture until fully combined.
Place the bowl over a pot of simmering water (double boiler), add a pinch of salt, and stir constantly for 10–15 minutes, or until the curd thickens enough to coat the back of a spoon.
Remove from heat and stir in butter cubes, one at a time, until smooth.
Strain the curd again for a silky texture, then transfer to a jar or container.
Cool to room temperature, cover with plastic wrap pressed directly on the surface, and refrigerate for up to one week.

FAQs

Can I use frozen blueberries?

Yes, frozen blueberries work perfectly and don’t need to be thawed before cooking.

How can I make the curd thicker?

Cook the curd a bit longer over low heat, stirring constantly to avoid scrambling the eggs.

Can I make blueberry curd without a double boiler?

Yes, you can cook it directly in a saucepan over very low heat, but stir constantly and watch closely to prevent curdling.

Can I reduce the sugar in this recipe?

Yes, but keep in mind that sugar helps preserve the curd and balance the tartness.

What’s the best way to strain the curd?

Use a fine-mesh sieve and press gently with a spatula for a silky, lump-free texture.

Can I can blueberry curd for shelf storage?

No, curd is not safe for home canning due to its egg and butter content.

How do I prevent a skin from forming on the curd?

Press plastic wrap directly onto the surface before refrigerating.

Can I make this curd vegan?

You can try using plant-based butter and an egg substitute, though texture and flavor may differ.

What can I use blueberry curd for?

Spread it on toast, fill pastries, swirl into yogurt, or layer in cakes and desserts.
