Servings & Timing
- Servings: About 1½ cups (10–12 tablespoons)
- Prep Time: 5 minutes
- Cook Time: 10–12 minutes
- Total Time: 15–17 minutes
Ingredients List
- ½ cup (120 ml) fresh lemon juice (about 2–3 lemons)
- 2 tbsp lemon zest
- ½ cup (100 g) unsalted butter, cut into cubes
- ½ cup (100 g) powdered erythritol (or monk fruit sweetener)
- 4 large egg yolks (or 3 whole eggs for a lighter texture)
- Pinch of salt (optional, to balance flavor)
Instructions
Step 1: Prepare the Lemon Mixture
In a small saucepan (off the heat), whisk together the lemon juice, lemon zest, powdered erythritol, and egg yolks until fully combined and smooth.
Step 2: Cook Over Low Heat
Place the saucepan over low heat and stir constantly with a whisk or silicone spatula. Cook gently for 8–10 minutes, or until the mixture thickens enough to coat the back of a spoon. Do not let it boil — this can cause curdling.
Step 3: Add Butter
Once the lemon curd has thickened, remove it from the heat. Immediately whisk in the butter cubes, a few at a time, until the mixture becomes silky and glossy.
Step 4: Strain & Cool
(Optional but recommended) Strain the curd through a fine-mesh sieve into a clean bowl to remove any bits of zest or cooked egg. Let it cool to room temperature, then transfer to a jar or airtight container.
Step 5: Chill & Serve
Refrigerate for at least 1 hour before serving. The lemon curd will continue to thicken as it chills.
Additional Notes
- Sweetness Control: Adjust the amount of erythritol to taste depending on your sweetness preference. Monk fruit works beautifully for a smoother finish.
- Silky Texture Tip: Constant stirring and low heat are key to achieving a creamy, custard-like consistency without scrambling the eggs.
- Butter Choice: Salted butter can be used if you prefer a slightly richer, deeper flavor.
