How do you solve lumpy sauce?

1. Strain the sauce through a fine-mesh sieve. This will remove any lumps and create a smooth sauce.

2. Use a blender or food processor to puree the sauce. This will also break down any lumps and create a smooth sauce.

3. Add a small amount of liquid to the sauce and stir until smooth. This will help to thin out the sauce and make it less likely to form lumps.

4. Cook the sauce for a longer period of time. This will allow the sauce to thicken and the lumps to dissolve.

5. Add a cornstarch slurry to the sauce. This will help to thicken the sauce and prevent it from forming lumps.
