Gather all your ingredients. It's always easier to create magic when your workspace is organized. Separate your egg yolks from the whites, and set them aside in a mixing bowl.

In your mixing bowl with the egg yolks, add in the stone-ground mustard, raw cane sugar, white wine vinegar, and kosher salt. Whisk these ingredients together vigorously. You want to create a smooth mixture, incorporating the flavors well.

Next, pour this mixture into a saucepan. Over low heat, gently stir until the sugar dissolves. This should take just a few minutes. Be careful! You don’t want to scramble the eggs, so patience is key.

Once the sugar is dissolved, pour in the heavy whipping cream. Keep on that low heat, stirring constantly. This step is essential for achieving that creamy consistency. Continue cooking until the mixture slightly thickens, about 5 to 7 minutes.

Remove the sauce from heat. Stir in the freshly grated lemon zest and smoked paprika (if using). These notes of flavor elevate the sauce, adding depth.

Allow the sauce to cool slightly before serving. It can be enjoyed warm or chilled. A drizzle over your favorite dish or a simple dip for veggies – the choice is yours!
