Method
- 1.
Whisk the lemon base — In a large microwave-safe bowl or jug, whisk together the egg yolks, whole egg, white sugar, lemon juice, and lemon zest until smooth.
- 2.
Stir in the butter — Add the cubed butter and stir it into the mixture.
- 3.
Microwave in short bursts — Microwave on medium power (about 50%) in 30-second bursts, whisking vigorously between each one, for a total of 3-4 minutes. This gentle, repeated burst-and-whisk method is essential to stop the eggs from scrambling.
- 4.
Check the curd's thickness — Check the consistency after each burst by running a spoon through the curd: it is ready when it thickens enough to coat the back of the spoon.
- 5.
Cool and chill the curd — Stir in the vanilla extract, let the lemon curd cool slightly, then chill before serving over scones or as a dessert topping.
