<human>:  How do I fix the runny sauce I made?
<bot>: The first step to fixing a runny sauce is to thicken it. You can do this by reducing the liquid in the sauce, either by boiling it until it has reduced by the desired amount or adding a thickening agent like cornstarch or a roux. Alternatively, you can add ingredients like cheese, cream, or egg yolks, which will help to thicken the sauce. Whichever method you choose, make sure that you stir constantly and keep an eye on the consistency to ensure that you don't overdo it.
