Why is my roux not thickening?

A colleague describes perfect roux as “wet sand at low tide”: moist but not runny. As a roux cooks, it gets darker and its flavor becomes more complex. It’s important to understand, however, that as a roux colors, it loses its ability to thicken because the starch in the flour is broken down by the heat.

How long should you cook a roux?

White roux is cooked for 2–5 minutes, just long enough to get rid of the raw flour taste, take on a light tan color, and achieve the texture of wet sand. Butter is usually the fat of choice. White roux is used to thicken sauces without adding much flavor, like in béchamel, a classic white sauce.

Why is my Roux separating?

If it’s too cold it hardens the butter, and if it’s too hot it can separate the roux. The way roux thickens a liquid is by the starch molecules in the flour absorb the liquid and expand, becoming slightly gelatinous, which creates the effect of thickening the sauce.
