The best lemon tart recipe ever also happens to be super easy! Learn how to make classic French Tarte au Citron that tastes like it came from a French patisserie!
To make the lemon curd: Start by zesting the lemons (about 2 whole lemons) directly into the sugar and rub the zest into the sugar.
In a medium heatproof metal bowl, place eggs, lemon sugar, lemon juice, a pinch of salt and heavy cream and whisk to combine. Place the bowl over a saucepan of simmering water (bain-marie).
Cook on moderate heat, whisking constantly until the mixture becomes nice and thick. This can take a good 15 minutes. As a shortcut, you can skip the water bath and make it on the stovetop but be careful to not heat it too quickly.
