Roux
A roux (pronounced "roo") is a thickening base for sauces, gravies, and soups, made from equal parts fat (like butter) and flour cooked together, then combined with a liquid like milk or broth. The cooking time determines its color and flavor, ranging from a white roux (cooked briefly for creamy sauces) to a blonde roux (nutty flavor for veloutés) to a brown roux (deep, rich flavor for gumbo). It's a fundamental technique for creating smooth, lump-free sauces.
Scaled Formulation Weights
Kitchen Execution Note: Always cook your structural fat and flour mix together for a minimum of 2 minutes to cook out the raw starch flavor before processing liquid feeds.
Core Preparation Blueprints
- Melt your calculated Fat weight component in a heavy-bottomed saucepan over medium-low heat.
- Whisk in the matching Flour weight calculation completely until a smooth, uniform paste forms.
- Cook the paste to your targeted target profile requirement:
- White/Blond Roux: Cook 2–4 mins until pale, bubbly, and smelling faintly nutty.
- Brown/Dark Roux: Cook 15–30 mins stirring constantly until a deep chocolate aroma and hazelnut coloration maps.
- Slowly stream your parent recipe's active liquid volume metric into the hot roux while whisking vigorously to eliminate lumps, then simmer until fully thickened.
