Ingredients for Grandmother’s Mustard Sauce
4 large egg yolks (60 g approximately)
4 tablespoons (24 g) stone-ground mustard
½ cup (114 g) raw cane sugar
¼ cup (70 g) aromatic white wine vinegar
1 teaspoon (4 g) fine kosher salt
1 cup (240 g) heavy whipping cream
½ teaspoon freshly grated lemon zest
¼ teaspoon smoked paprika (optional)

Step-by-Step Instructions
Step 1: Prepare Your Ingredients
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.
Step 2: Mix the Base
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.
Step 3: Heat it Up
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.
Step 4: Add the Cream
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.
Step 5: Final Touches
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.
Step 6: Cool and Serve
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!
Notes
Whisk Well: Ensure you whisk thoroughly in the beginning to avoid lumps.
Temperature Matters: Keep the heat low while mixing the ingredients to prevent curdling.
Adjust Flavor: Feel free to tweak the amount of mustard or sugar for your taste.
Make it Ahead: This sauce can be made in advance and stored in the fridge. It develops flavor as it sits!
Experiment: Don’t hesitate! Add your unique twist with herbs or spices to customize it.

What are Some Alternative Choices to the Ingredients?
Mustard Alternatives: If you don’t have stone-ground mustard, Dijon mustard can work just fine. Just note that the texture and sharpness will vary slightly.
Sweetener: In place of raw cane sugar, try honey or agave syrup. They add a sweetness that subtly complements the sauce.
Vinegar Substitute: If white wine vinegar isn’t available, apple cider vinegar works as a fantastic alternative with a slightly different tang.
Cream Options: For a lighter version, substitute the heavy whipping cream with Greek yogurt or sour cream. This will alter the texture but will still create a delicious sauce!
