Lavender Lemon Curd

Lavender lemon curd is a silky, tangy spread made by whisking egg yolks with lemon juice and zest over gentle heat, then stirring in butter and dried lavender. The result is bright, floral, and rich enough to top yogurt, spread on scones, or fill a cake. The key is keeping the heat low so the eggs thicken without scrambling.

Ingredients for Lavender Lemon Curd

Egg yolks are the base that thickens everything as they warm. Lemon juice and lemon zest provide the sharp citrus flavor. Sugar sweetens and helps the mixture thicken. Butter makes it rich and silky. Dried culinary lavender brings floral notes without harshness. Salt balances the sweetness and brightens the lemon.

Why This Lavender Lemon Curd Works

Egg yolks contain an emulsifier that holds butter and juice together as they warm, turning thin and watery into thick and creamy. The heat must stay low enough that the yolks cook gently without turning scrambled and grainy. If the mixture gets too hot, the proteins clump instead of staying smooth.

Lemon juice adds acid that cuts through the richness and keeps the curd from tasting one-note sweet. Lavender is dried and strained out at the end so you get its flavor without bits of stem or flower in every spoonful. The finished curd keeps in the refrigerator for two weeks and freezes for up to three months.

Mistakes To Avoid

Cooking over heat that is too high turns the eggs into scrambled bits instead of a smooth sauce. The mixture will look grainy and curdled and will not come back together. Always use medium or medium-low heat and stir constantly.

Adding the butter too fast before the eggs are thick enough causes the curd to break and separate. The fat and liquid split apart and will not recombine. Add butter in small pieces only after the mixture coats the back of a spoon.

Forgetting to strain out the lavender leaves bits of stem and flower in the finished curd, which tastes like eating plant material. Pour the hot curd through a fine mesh sieve into a bowl, pressing gently with a spoon to push the liquid through.

Using bottled lemon juice instead of fresh changes the acid level and may throw off both the flavor and the way the curd sets. The result tastes flat and may not thicken properly. Squeeze fresh lemons and measure the juice by volume.

Ingredients

• 5 egg yolks
• 1/2 cup (100 grams) sugar
• 1/2 cup fresh lemon juice
• 2 tablespoons lemon zest
• 6 tablespoons (85 grams) unsalted butter, cut into small pieces
• 2 teaspoons dried culinary lavender
• 1/4 teaspoon salt

Step-by-step Instructions

1. Combine egg yolks, sugar, lemon juice, lemon zest, and dried lavender in a medium saucepan.
2. Whisk together over medium-low heat for 12 to 15 minutes, stirring constantly, until the mixture reaches 160°F (71°C) on an instant-read thermometer and coats the back of a spoon.
3. Remove from heat and immediately strain the curd through a fine mesh sieve into a clean bowl, pressing gently with a spoon to push the liquid through and leave the lavender behind.
4. Stir the salt into the strained curd.
5. Add the butter pieces one at a time, stirring until each piece melts completely before adding the next.
6. Press plastic wrap directly onto the surface and let cool to room temperature, about 30 minutes.
7. Transfer to jars or containers and refrigerate until ready to use.
