In a small saucepan, melt the unsalted butter over medium heat.
Whisk in the all-purpose flour, cooking for about 1 minute to form a smooth roux. Do not let it brown.
Gradually whisk in the milk, stirring constantly to avoid lumps. Bring the mixture to a gentle simmer.
Once the mixture thickens slightly, reduce the heat to low and stir in Dijon mustard and whole-grain mustard.
Stir in the lemon juice, salt, and black pepper. Adjust seasoning to taste.
Allow the sauce to gently simmer for another 1-2 minutes to blend the flavors, stirring frequently.
Remove from heat and let the sauce cool for 1-2 minutes before serving.
Optionally, garnish with freshly chopped dill for added flavor and presentation.
Serve the mustard sauce warm over your favorite cooked fish, such as salmon, cod, or tilapia.
