Ingredients
- 1 tablespoon butter

- 1 cup vegetable broth

- 1 tablespoon Dijon mustard
- 1 tablespoon coarse grain mustard
- 2 tablespoons sesame seeds (toasted or not)

Instructions
- Step 1: Melt the butter in a medium saucepan over medium-low heat. Whisk in the flour and cook, whisking constantly, for 3 minutes to form a roux.

- Use chicken or vegetable broth depending on your dietary preference.
- Add a splash of cream for an even richer sauce.

Storage
Store any leftover sauce in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove over low heat, stirring frequently to maintain a smooth texture. If the sauce thickens too much upon cooling, add a splash of broth or water to loosen it.
