Can you make bechamel sauce with cornstarch?

You can make a sauce similar to béchamel using cornstarch, but it won't be true béchamel. Here's why:

* Béchamel's defining characteristic is its roux, a mixture of butter and flour. Cornstarch doesn't form a roux the same way flour does.

* Cornstarch-based sauces tend to be thinner and have a slightly different taste. They don't have the same rich, velvety texture of béchamel.

Here's how to make a cornstarch-based sauce similar to béchamel:

1. Whisk together cornstarch and cold milk. This prevents lumps from forming.

2. Heat the milk mixture gently over medium heat. Stir constantly until the sauce thickens.

3. Season with salt, pepper, and nutmeg (if desired).

To achieve a texture closer to béchamel:

* Use a higher ratio of cornstarch to milk. This will result in a thicker sauce.

* Add a bit of butter at the end. This will add richness and shine.

Remember: This sauce will not be a true béchamel, but it can be a tasty alternative if you need a quick and easy sauce.

For a truly authentic béchamel, stick to the traditional method using butter and flour.
