Understanding Roux

A roux, at its core, is a simple yet transformative mixture of flour and fat, skillfully combined to thicken and enrich sauces, soups, and stews. The process begins by melting your chosen fat in a pan—be it butter, oil, or any fat substitute.

A lighter roux retains more thickening power but less flavor, while a darker roux offers a complex, nutty flavor with reduced thickening ability. The fat used in the roux, from butter to olive oil, can also influence the dish's final taste, making the selection of fat a crucial step in aligning with your culinary goals.
