Blackberry Curd Recipe: Tangy Spread for Toasts & Desserts

With the ideal balance of tartness and sweetness, this luscious blackberry curd is an excellent way to make the most of peak-season blackberries.

While lemon and lime curds often take center stage, blackberry curd delivers a vibrant, summery flavor that stands out. It has a silky, buttery texture and brings a bright berry note to cakes, cupcakes, and pastries.

Ingredients

Below are a few tips about the most important ingredients. The complete ingredient list and measurements appear in the recipe card further down.

Egg yolks and a whole egg: Using two yolks plus one whole egg creates a rich, dense curd without an overly eggy taste.
Fresh blackberries: Ripe, fresh berries give the best flavor and color for the curd.
Unsalted butter: Adds creaminess and depth. Measure carefully—too much butter can mute the fruit’s brightness.
Lemon juice: Provides a bright tang and helps the curd set evenly.

How to make blackberry curd

Small mesh sieve over a glass pyres measuring cup with pureed blackberry being worked through it.

First, puree the blackberries until smooth. Push the puree through a fine-mesh sieve with a spatula to remove seeds and coarse pulp, collecting about ½ cup of strained blackberry puree.

Second, combine everything except the butter—sugar, lemon juice, eggs, and the strained blackberry puree—in a heatproof bowl. Set the bowl over a pot of simmering water and cook, whisking occasionally, until the mixture thickens and coats the back of a wooden spoon, about 10 minutes. Remove from heat and let cool for about 10 minutes, then whisk in the cubed butter until fully incorporated.

Finally, press plastic wrap directly on the curd’s surface to prevent a skin from forming, then refrigerate until completely set. Use the curd to fill cakes, swirl into yogurt or pastries, or simply spread it on toast. A blackberry layer in a cake is one of my favorite uses.

Expert tips

Under-ripe blackberries: If berries are not fully ripe, cook them briefly over medium heat to help release juices before pureeing.
Use a non-white spatula: Berry juice can stain, so choose a silicone spatula in a darker color when pressing the puree through the sieve.
Fresh lemon juice: Freshly squeezed lemon juice gives the best flavor and acidity control.
Check doneness: The curd is ready when it thickly coats the back of a wooden spoon.

Substitutions

Frozen blackberries: If fresh berries aren’t available, thaw frozen blackberries to about room temperature (microwave 1–2 minutes if needed) before pureeing and straining.

Vegan blackberry curd: Replace the egg with a cornstarch slurry—stir 2 tablespoons cornstarch into 1/3 cup non-dairy milk, then proceed with the recipe, cooking until thickened. Stir in 4 tablespoons vegan butter in place of the regular butter.

Storage

Store blackberry curd in the refrigerator for up to seven days or freeze for up to three months. Thaw frozen curd in the refrigerator overnight before using.

Using leftover egg whites

This recipe leaves two unused egg whites. They can be used for meringues, a light frosting, or tucked into other baked goods. Egg whites can be kept in the fridge for up to two days or frozen for up to three months—freeze individually in an ice cube tray and thaw overnight in the refrigerator.
