What can you do to stop dry starchy lumps in your sauce?

To prevent dry starchy lumps in your sauce, make sure to properly hydrate any flour or starch before adding it to the liquid. You can create a slurry by mixing the starch with a small amount of cold water or broth before adding it to the sauce. Additionally, whisk the sauce continuously while incorporating the starch to ensure even distribution and prevent clumping. If lumps do form, you can use an immersion blender or strain the sauce to achieve a smooth consistency.
