Ingredients
Method
- Add the granulated sugar and lemon zest to a medium bowl. Rub them together with your fingertips for 1 to 2 minutes until the sugar becomes fragrant and slightly damp.
- Whisk in the eggs and egg yolks until smooth. Add the fresh lemon juice and salt, then whisk until fully combined.
- Pour the mixture into a heavy-bottomed saucepan and cook over medium-low heat, stirring constantly with a silicone spatula.
- Continue cooking until the curd thickens to 170 to 175°F, or until it coats the back of a spoon and a finger drawn through it leaves a clean line.
- Remove the saucepan from the heat and whisk in the cold butter a few cubes at a time until completely melted and smooth.
- Pour the curd through a fine-mesh sieve into a clean bowl to remove any bits of cooked egg or zest for an ultra-silky texture.
- Press plastic wrap directly onto the surface of the curd to prevent a skin from forming. Refrigerate for at least 2 to 3 hours, or until fully chilled and set.
Notes
- Use fresh lemons. Freshly squeezed juice and zest give the curd its bright, natural flavor that bottled juice can’t match.
- Rub the zest into the sugar. This step releases the lemon oils and deepens the citrus aroma before cooking.
- Cook low and slow. Keep the heat on medium-low and stir constantly to prevent the eggs from curdling.
- Watch for the right texture. The curd is ready when it coats the back of a spoon and leaves a clean line when you run your finger through it.
- Add butter gradually. Whisk in a few cubes at a time so it melts evenly and creates a smooth, glossy finish.
- Strain for silkiness. Passing the curd through a fine-mesh sieve removes any bits of zest or cooked egg for a perfectly smooth texture.
- Chill completely. Let the curd set in the fridge for at least 2–3 hours before serving for the best consistency.
- Store properly. Keep the curd in an airtight container in the fridge for up to a week or freeze for up to two months.
- Make ahead. Lemon curd holds up beautifully, so you can prepare it a few days in advance for easy desserts or breakfast spreads.
