Prep and Cook Time
- Preparation: 10 minutes
- Cooking (Sous Vide): 45 minutes
- Chilling: 2 hours (recommended for best texture)
Yield
Approximately 1 cup of lemon curd, enough for 6 servings as a spread or dessert topping.
Difficulty Level
Medium - requires minimal equipment but attention to detail in temperature control.
Ingredients
- 3 large organic egg yolks
- 3/4 cup granulated sugar
- 1/2 cup freshly squeezed lemon juice (about 2 lemons)
- 1 tablespoon finely grated lemon zest
- 6 tablespoons unsalted butter, cut into cubes and chilled
- pinch of fine sea salt
Step-by-step Instructions
- Prepare your sous vide water bath: Set your immersion circulator to 82°C (180°F). this temperature allows gentle, consistent cooking, preventing curdling while activating natural thickening.
- Combine the base ingredients: In a heat-safe mixing bowl, whisk the egg yolks, sugar, lemon juice, lemon zest, and pinch of salt until fully integrated and slightly pale.
- Bag and seal: Pour the mixture into a high-quality, sous vide-safe bag or heatproof jar. Remove as much air as possible using a vacuum sealer or the displacement method.
- Cook sous vide: Submerge the sealed bag or jar entirely in the water bath. Cook for 45 minutes, gently stirring every 15 minutes to encourage even thickening. You’ll notice the mixture transform into a creamy custard.
- Add butter for silkiness: Once cooked, remove the bag or jar from the bath. Quickly whisk in the cold butter cubes one by one until fully melted and emulsified, enhancing the curd’s velvety mouthfeel.
- Strain for smoothness (optional): Pass the lemon curd through a fine mesh sieve into a clean bowl to eliminate any residual curdled bits or zest pieces.
- Chill and thicken: Cover the curd with plastic wrap pressed directly on the surface to prevent skin formation. Refrigerate for at least 2 hours for the flavor and texture to fully meld.
Tips for Success
- Egg yolks: Use fresh and room temperature yolks for even cooking.
- Temperature Matters: Stick strictly to 82°C (180°F).Lower temps cause runny curd; higher temps risk scrambling.
- Butter choice: Use unsalted for true flavor control and better emulsification.
- Make-ahead: Lemon curd stored in an airtight jar stays fresh for up to 1 week refrigerated or 3 months frozen.
- Flavor twists: Add a splash of vanilla extract or swap half the lemon juice for lime for a citrus medley.
- Leftover critter: Overcooked curd? Rescue by blending with a blender, adding a little warm water to loosen.
