How To Make A Roux

A roux is a classic French base of a dish, and used in soups, stews, sauces, and gravies. It’s used to thicken and add flavor to a dish, and it’s a simple technique that anyone can master.

Step-by-Step Guide:

1. Melt the butter in a saucepan over moderate heat. If you’re using oil, then you can skip this step.

2. Add the flour and mix the butter until it’s fully combined. Make sure the flour and butter are mixed properly, so it doesn’t form lumps, which can affect the texture of the sauce.
