Ingredients:
- 1 tablespoon (6g) fresh orange zest
- 3/4 cup (180ml) freshly squeezed orange juice
- 1 tablespoon (15ml) fresh lemon juice
- 3/4 cup (150g) granulated sugar
- 4 large egg yolks
- 1 large whole egg
- 1/2 cup (115g) unsalted butter, cold and cubed
- 1 pinch fine sea salt
Instructions:
- Zest the oranges directly over the sugar. Rub the zest into the sugar with your fingertips until fragrant to release the essential oils.
- In a heat-proof glass or stainless steel bowl, whisk together the citrus-infused sugar, egg yolks, and the whole egg until pale and slightly frothy.
- Slowly whisk in the orange juice, lemon juice, and salt until well combined.
- Place the bowl over a saucepan of simmering water to create a double boiler, ensuring the bottom of the bowl does not touch the water.
- Whisk constantly for 10 to 15 minutes until the mixture thickens to a pudding-like consistency that coats the back of a spoon (170°F/77°C).
- Remove from heat and add cold, cubed butter one piece at a time, whisking until each piece is fully melted and the curd is glossy.
- Immediately pour the curd through a fine-mesh sieve into a clean bowl to remove the zest and any cooked egg fragments.
- Press plastic wrap directly onto the surface to prevent a skin from forming and refrigerate for at least 3 hours to set.
