What Is Raspberry Curd?

Raspberry curd is a creamy fruit spread made by gently cooking raspberries with egg yolks, butter, lemon juice, and sweetener.

Traditional raspberry curd is usually made with granulated sugar. This keto raspberry curd uses a sugar substitute instead, giving you the same rich texture and fruity flavor without the added sugar.

The egg yolks and butter naturally thicken the mixture as it cooks. Once chilled, the curd becomes even thicker and easier to spread or use as a dessert filling.

What's great about a true curd recipe is that it's thickened naturally with just butter and egg yolks, so it's gluten-free.

And in the case of raspberries, their high level of pectin also thickens the curd beautifully.

• Fresh or frozen raspberries
• Granulated sugar-substitute
• Unsalted butter softened
• Lemon juice
• Egg yolks, room temperature
• Sea salt

Tools You'll need

You'll need just a few tools to make this recipe most of which you hopefully already have on hand. 

The recipe calls for the use of a double-boiler.  This is to ensure that the raspberry curd doesn't scorch. However, you don't have to use anything fancy.

I simply make my own by using a 4-quart glass bowl so that it is large enough to fit over a pot of boiling water.

The key is to make sure the water is never touching the glass bowl. You are cooking with steam here and not direct heat.

• Fine mesh strainer to remove the seeds
• Wooden spoon
• Wisk
• Jar, lidded storage container

Fresh or Frozen Raspberries

You can make this raspberry curd recipe with either fresh or frozen raspberries.

Fresh raspberries are wonderful when they are in season, but frozen raspberries allow you to enjoy this recipe throughout the year.

When using frozen raspberries, thaw them completely before adding them to the recipe. Drain away any excessive liquid that collects after thawing so that the finished curd does not become too thin.

Frozen berries may also require a few additional minutes of cooking because they can release more moisture than fresh raspberries.

How To Make A Sugar-Free Raspberry Curd 

Begin by preparing a double boiler. The bottom of the bowl should sit above the simmering water without touching it. This gentle heat helps prevent the egg yolks from cooking too quickly.

Melt the butter in the double boiler. Add the raspberries, lemon juice, sugar substitute, and salt. Stir frequently while gently crushing the raspberries with a spoon as they soften.

Reduce the heat and gradually whisk in the egg yolks. Continue cooking and stirring until the raspberry mixture thickens enough to coat the back of a spoon.

Press the finished curd through a fine-mesh strainer to remove the raspberry seeds and any small pieces of cooked egg. Allow it to cool before transferring it to a covered glass container.

The raspberry curd will continue to thicken as it chills in the refrigerator.

How to Tell When Raspberry Curd Is Done

The raspberry curd is ready when it has visibly thickened and coats the back of a spoon.

Run your finger across the coated spoon. If the line remains visible and the curd does not immediately flow back together, it is usually thick enough.

Avoid allowing the mixture to boil because high heat can cause the egg yolks to scramble. Keep the heat low and stir or whisk frequently throughout the cooking process.

Ways to Use Raspberry Curd

This sugar-free raspberry curd can be used as a spread, topping, filling, or simple dessert.

Try serving it with:

• Keto Scones
• Keto Pound Cakes
• Keto Dutch Baby Pancake
• Keto Waffles
• Plain Greek Yogurt
• Low-Carb Toast

Sugar-Substitutes For Raspberry Curd

I have several options regarding which sweetener you can use in this sugar-free curd. I happen to be partial to Lakanto Monk Fruit.

I'm also a big fan of the brand Swerve which is an erythritol blend. Like Lakanto, it uses sugar alcohols and has a 0% impact on blood sugar.

You could also use the stevia and erythritol-based brand Pyure if you prefer to use a stevia-based sweetener. 

I don't like using stevia because I am sensitive to the aftertaste. But if that's not the case for you, you could certainly use it in this recipe.

Remember that if this is your pick, ensure you reduce the amount called for in the recipe by half since a stevia-based option is much sweeter.

Lastly, if you can't easily find a more natural sugar substitute, you can also use Splenda with good success.

I know not everyone would agree with me here, and I respect that, but in my book, it's still better than regular sugar. 

Is Raspberry Curd Keto-Friendly?

Traditional raspberry curd is usually made with a substantial amount of sugar and is not considered keto-friendly.

This low carb raspberry curd recipe replaces regular sugar with a keto-friendly sweetener. Each tablespoon contains approximately 0.9 grams of net carbohydrates, based on the nutrition information in the recipe card.

Can I Use Raspberry Curd as a Cake Filling?

Yes. This thick raspberry curd makes a flavorful filling for keto vanilla, chocolate, lemon, almond, or coconut cakes.

Chill the curd completely before using it. Cold raspberry curd will be thicker and less likely to run out between the cake layers.

Why Is My Raspberry Curd Not Thickening?

Raspberry curd may remain thin if it has not cooked long enough, if the heat is too low, or if frozen raspberries added excessive moisture.

Continue cooking it gently while stirring until it coats the back of a spoon. Remember that it will thicken considerably once it has cooled and chilled.

Do not increase the heat too aggressively because this can scramble the egg yolks.

Why Is My Raspberry Curd Lumpy?

Lumps usually develop when the egg yolks cook too quickly. This can happen if the heat is too high or the mixture is not stirred frequently enough.

Pressing the finished curd through a fine-mesh strainer will remove any small lumps along with the raspberry seeds.

How Long Does Raspberry Curd Last?

Store the cooled raspberry curd in a clean, airtight container in the refrigerator for up to one week.

Use a clean spoon each time you remove curd from the container to help keep it fresh.

Can You Freeze Raspberry Curd?

Yes. Transfer the completely cooled curd to a freezer-safe container, leaving a little room for expansion.

Freeze it for up to one month. Thaw it overnight in the refrigerator and stir it well before serving. The texture may be slightly softer after freezing, but it will still work well as a topping or dessert filling.

Is This A Carnivore Raspberry Recipe?

No. Although this raspberry curd contains several animal-based ingredients, including egg yolks and butter, it is not a carnivore recipe because it also contains raspberries and lemon juice.

A strict carnivore diet excludes fruit and other plant-based foods. This recipe is better described as keto, low-carb, sugar-free, and gluten-free.

Those following a more flexible animal-based diet that includes small amounts of fruit may choose to enjoy it, but it would not be suitable for a strict carnivore approach.
