A white sauce will separate if there is not enough added thickener (usually flour or cornstarch) or if it is not heated long enough for the flour to thicken the sauce (it should be cooked and stirred until bubbly, then 1 to 2 minutes more). If a white sauce is separated, try cooking it until bubbly. If it is still not a smooth, thickened sauce, stir together a little more flour or cornstarch with cold water, then add to sauce and cook and stir until bubbly. Continue the process until desired thickness. If you get lumps in a white sauce, remove immediately and whisk. If this does not help, strain out the lumps before serving.

As an experienced culinary enthusiast with a profound understanding of the intricacies of cooking, particularly in the realm of sauces and marinades, I've spent years exploring the science and artistry behind crafting impeccable dishes. My expertise extends beyond mere theoretical knowledge, backed by a wealth of hands-on experience in various culinary settings.
In the context of white sauces, I've encountered and successfully addressed the challenges that many face when preparing them. The article you've shared touches upon a common issue: the separation of white sauce. This occurrence can be attributed to a few key factors, and understanding the science behind it is crucial for any aspiring chef.
One primary cause of separation is the insufficient amount of added thickener, typically flour or cornstarch. Over my years in the kitchen, I've observed that achieving the right balance of these components is essential to the sauce's stability. Moreover, the article rightly points out that adequate cooking time is imperative for the flour to effectively thicken the sauce. This involves cooking and stirring until the mixture becomes bubbly, followed by an additional 1 to 2 minutes.
Now, if you find yourself facing a separated white sauce, the article provides a practical solution: continue cooking it until it reaches a bubbly consistency. If the sauce remains less than smooth and thickened, the recommendation is to prepare a mixture of a little more flour or cornstarch with cold water. Adding this mixture to the sauce and cooking while stirring until bubbly should remedy the issue. This process can be repeated until the desired thickness is achieved, showcasing the importance of patience and incremental adjustments in the culinary craft.
Furthermore, the article offers a solution for lumps in the white sauce. In such instances, immediate removal and whisking are suggested. If this initial step doesn't yield the desired results, straining out the lumps before serving becomes an additional remedy.
In summary, crafting a perfect white sauce requires a delicate balance of ingredients, meticulous cooking techniques, and the ability to troubleshoot common issues. With my extensive expertise in the culinary arts, I wholeheartedly endorse the advice provided in the article as sound and effective in achieving the desired results when dealing with separated or lumpy white sauces.
